Rockwell Collins, Inc. was a multinational corporation headquartered in Cedar Rapids , Iowa , providing avionics and information technology systems and services to government agencies and aircraft manufacturers . It was formed when the Collins Radio Company , facing financial difficulties, was purchased by Rockwell International in 1973. In 2001, the avionics division of Rockwell International was spun off to form the current Rockwell Collins, Inc., retaining its name.
73-587: The company was acquired by United Technologies Corporation on November 27, 2018, and now operates as part of Collins Aerospace , a subsidiary of the RTX Corporation (formerly Raytheon Technologies). Arthur A. Collins founded Collins Radio Company in 1933 in Cedar Rapids, Iowa . It designed and produced both shortwave radio equipment and equipment for the AM radio broadcast industry. Collins supplied
146-460: A broadcast transmitter , a transmitter used in broadcasting , as in FM radio transmitter or television transmitter . This usage typically includes both the transmitter proper, the antenna, and often the building it is housed in. A transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. A transmitter and a receiver combined in one unit
219-472: A frequency modulation (FM) transmitter, it is added by varying the radio signal's frequency slightly. Many other types of modulation are also used. The radio signal from the transmitter is applied to the antenna , which radiates the energy as radio waves. The antenna may be enclosed inside the case or attached to the outside of the transmitter, as in portable devices such as cell phones, walkie-talkies, and garage door openers . In more powerful transmitters,
292-429: A radio frequency signal which when applied to the antenna produces the radio waves, called the carrier signal . It combines the carrier with the modulation signal, a process called modulation . The information can be added to the carrier in several different ways, in different types of transmitters. In an amplitude modulation (AM) transmitter, the information is added to the radio signal by varying its amplitude . In
365-566: A few years, Collins had introduced additional S/Line components, including the 30S-1 kilowatt power amplifier, the 30L-1 desktop power amplifier, and the 62S-1 transverter , which provided coverage of the 6-m (50 MHz) and 2-m (144 MHz) amateur bands. The KWM-2 transceiver replaced the KWM-1 using many of the S/Line's design features and matching its styling. Other accessories included speakers, microphones, and control consoles. Illustrating
438-657: A goal of automating all functions from parts ordering and inventory to factory scheduling to generation of maintenance provisioning. With products technically successful and far ahead of their time in many respects, Mr. Collins continued to invest in development at a rate that could not be supported by sales when a downturn occurred, and began to have financial problems. In 1991, Rockwell sold its Richardson, Texas-based Network Transmission Systems division to Alcatel . In 2008, Rockwell Collins acquired Athena Technologies for US$ 107 million (equivalent to $ 151.42 million in 2023). In August 2013, Rockwell Collins announced
511-518: A high voltage spark between two conductors. Beginning in 1895, Guglielmo Marconi developed the first practical radio communication systems using these transmitters, and radio began to be used commercially around 1900. Spark transmitters could not transmit audio (sound) and instead transmitted information by radiotelegraphy : the operator tapped on a telegraph key which turned the transmitter on-and-off to produce radio wave pulses spelling out text messages in telegraphic code, usually Morse code . At
584-544: A newly created direct or indirect subsidiary of Rockwell, Quarterback Merger Sub Corp., merged with and into B/E Aerospace, with the latter surviving the merger as a direct or indirect subsidiary of Rockwell Collins. Rockwell Collins has five main divisions: The CS division services the commercial airline industry and business aircraft, providing navigation, communication, synthetic vision , other cockpit products such as autoland autopilots , and cabin products such as in-flight entertainment. The GS division services primarily
657-413: A radio wave. A radio transmitter is an electronic circuit which transforms electric power from a power source, a battery or mains power, into a radio frequency alternating current to apply to the antenna, and the antenna radiates the energy from this current as radio waves. The transmitter also encodes information such as an audio or video signal into the radio frequency current to be carried by
730-498: A receiver of the highest performance available, with the ruggedness and serviceability required for military duty. It featured direct mechanical digital frequency readout. The set is composed of several modules for easy field repair—a bad module could simply be swapped out and repaired later, or junked. Sets built during the original 1951 contract cost the government about US$ 2,500 (equivalent to $ 29,346 in 2023) each, and around 16,000 were produced. Concurrently, Collins developed
803-559: A replacement for the higher-performance R-390A, and unlike the R-390A, it was extensively marketed for commercial use. Collins produced a few high-performance solid-state receivers in the 1970s, such as the 651S-1. Like their tube predecessors, these are coveted by collectors today. With the introduction of the S/Line in 1958, Collins moved from designing individual products that could be used together, to ones that were designed to integrate and operate together, in various combinations, as

The invention of the transistor allowed the development in the 1960s of small portable transmitters such as wireless microphones , garage door openers and walkie-talkies . The development of the integrated circuit (IC) in the 1970s made possible the current proliferation of wireless devices , such as cell phones and Wi-Fi networks, in which integrated digital transmitters and receivers ( wireless modems ) in portable devices operate automatically, in
1825-399: The -3 and -3B units, respectively, except they provided an extra set of heterodyne oscillator crystals, enabling them to cover extra bands – useful for military, amateur and MARS operation, where operation just outside the regular amateur bands was necessary. Among amateur radio operators, the S/Line established its reputation as perhaps the most solidly engineered equipment available, and
1898-685: The 1920s. All these early technologies were replaced by vacuum tube transmitters in the 1920s, which used the feedback oscillator invented by Edwin Armstrong and Alexander Meissner around 1912, based on the Audion ( triode ) vacuum tube invented by Lee De Forest in 1906. Vacuum tube transmitters were inexpensive and produced continuous waves , and could be easily modulated to transmit audio (sound) using amplitude modulation (AM). This made AM radio broadcasting possible, which began in about 1920. Practical frequency modulation (FM) transmission
1971-487: The 212A1 and 212B1 replaced the 12H design. Collins became the principal supplier of radio and navigation equipment used in the military. In the postwar years, the Collins Radio Company expanded its work in the communications field, while broadening its technology into flight-control instruments, radio-communication devices, and satellite voice transmissions. Collins Radio Company provided communications for
2044-464: The 32V-1, -2, and -3, the KWS-1, and the rack-mounted KW-1. Around 1947, the company introduced their first amateur radio receiver, the 75A-1 (called the 75A). This set achieved excellent stability for the time due to high build quality and the use of a permeability tuned oscillator in its second conversion stage. It was one of the few double-conversion superheterodynes on the market, and covered only
2117-537: The Carrier deal was forcible, while the Mostek deal was a white knight move against hostile takeover designs by Gould . At one point, the military portion of UTC's business, whose sensitivity to "excess profits" and boom/bust demand drove UTC to diversify away from it, actually carried the weight of losses incurred by the commercial M&A side of the business. Although M&A activity was not new to United Aircraft,
2190-459: The Collins Radio Company constructed and sold transmitters and audio mixing consoles to the broadcast industry. In 1939, the model 12 Speech Input Console, in addition to the 26C limiter amplifier, was licensed to Canadian Marconi Co. for both sales in Canada and His Majesty's Service for the war effort. Collins' success in constructing broadcast transmitters continued to grow, selling well over
2263-522: The Collins Radio Company was purchased by Rockwell International in 1973. In 2001, the avionics division of Rockwell International was spun off to form Rockwell Collins, Inc, retaining its name. Rockwell Collins was highly concentrated in the defense and commercial avionics markets, and no longer marketed receivers to the public. On April 28, 2000, Rockwell International Corp and its Rockwell Collins unit agreed to acquire Sony Corp's Sony Trans Com ( Irvine, California ) for undisclosed terms. Sony had purchased

Electromagnetic waves are radiated by electric charges when they are accelerated . Radio waves , electromagnetic waves of radio frequency , are generated by time-varying electric currents , consisting of electrons flowing through a metal conductor called an antenna which are changing their velocity and thus accelerating. An alternating current flowing back and forth in an antenna will create an oscillating magnetic field around
3358-461: The background, to exchange data with wireless networks . The need to conserve bandwidth in the increasingly congested radio spectrum is driving the development of new types of transmitters such as spread spectrum , trunked radio systems and cognitive radio . A related trend has been an ongoing transition from analog to digital radio transmission methods. Digital modulation can have greater spectral efficiency than analog modulation ; that
3431-886: The business from Sundstrand Corporation in 1989. On December 20, 2000, Rockwell Collins expanded its services to commercial and executive aviation in Mercosur countries. The company had acquired several companies, including Hughes-Avicom's in-flight entertainment business (1998), Sony Trans Com (2000), Intertrade Ltd., Flight Dynamics, K Systems, Inc.

3504-561: The commercial market surviving the drastic cost-cutting market of the 1960s and 1970s. The transmitter line was later sold to Continental Electronics , which continued to produce a number of Collins designs under its own nameplate before phasing them out in the 1980s. Collins produced several shortwave transmitters to the commercial market. A "30" Series production catered to the growing need of state highway patrol agencies and Department of Commerce aviation needs. During World War II, Collins produced high-power transmitters for aircraft, notably
3577-419: The conductor. The alternating voltage will also charge the ends of the conductor alternately positive and negative, creating an oscillating electric field around the conductor. If the frequency of the oscillations is high enough, in the radio frequency range above about 20 kHz, the oscillating coupled electric and magnetic fields will radiate away from the antenna into space as an electromagnetic wave,
3650-498: The equipment. The Collins Collectors Association and the Collins Radio Association are two examples of such organizations. Groups of Collins users also organize meetings, gatherings at hamfests , and regularly scheduled on-air discussions called nets . In December 2019, CNBC listed Rockwell Collins along with 91 additional Fortune 500 companies that "paid an effective federal tax rate of 0% or less" as
3723-406: The heart of the S/Line, operated separately or together to transceive. The units included crystal band-pass filters and a new compact design that provided stable, highly linear tuning across 200 kHz band segments . The S/Line tuning-dial mechanism was unique when introduced. It used concentric dials and a gear mechanism that provided precise dial resolution, better than 1 kHz. Within

#17327978841703796-492: The intent to diversify into numerous high tech fields beyond aerospace. (The change became official on May 1, 1975.) The diversification was partially to balance civilian business against any overreliance on military business. UTC became a mergers and acquisitions (M&A)–focused organization, with various forced takeovers of unwilling smaller corporations. The next year (1976), UTC forcibly acquired Otis Elevator . In 1979, Carrier Refrigeration and Mostek were acquired;
3869-410: The late 1960s. In 1958, Collins replaced the 75A series with the much smaller 75S series, part of the S/Line. These featured mechanical filters, very accurate frequency readout, and excellent stability. At the request of the US government, Collins designed the 51S-1 general-coverage set, which was essentially (in intended use) a physically smaller replacement for the 51J series. It was not intended as
3942-464: The military, the scientific community, and the larger AM radio stations with equipment. Collins provided the equipment to establish a communications link with the South Pole expedition of Rear Admiral Richard E. Byrd in 1933. In 1936, Collins had begun production of the 12H audio console, 12X portable field announcers box, and the 300E and 300F broadcast transmitters. Throughout World War II ,
4015-463: The most costly. As a result, S/Line equipment, and the A-Line and other predecessors, are restored, prized, and operated on the air by collectors today. Collins continued to produce the S/Line well into the late 1970s, and after its acquisition by Rockwell. In 1978, with the move to solid-state design, the S/Line came to an end after a two-decade production run. The KWM-380 transceiver was introduced
4088-607: The new Rockwell, which then had $ 8.1 billion in revenues and $ 1.9 billion in pretax earnings with nearly 30,000 employees. Rockwell Collins filed for regulatory approval for its intended acquisition of B/E Aerospace, before the Philippine Competition Commission , since the latter has a branch in the Philippines operating a manufacturing plant in Tanauan, Batangas. As a result of the acquisition,

Modern designs more commonly use an oscillator at the operating frequency which is stabilized by phase locking to a very stable lower frequency reference, usually a crystal oscillator. Two radio transmitters in the same area that attempt to transmit on
4307-500: The previous fiscal cycle. United Technologies shares traded at over $ 114 per share, and its market capitalization was valued at US$ 98.6 billion in October 2018. UTC ranked No. 51 in the 2018 Fortune 500 list of the largest United States corporations by total revenue. During the 2004 election cycle , UTC was the sixth largest defense industry donor to political campaigns, contributing a total of $ 789,561; 64% went to Republicans. In
4380-400: The radio waves. When they strike the antenna of a radio receiver , the waves excite similar (but less powerful) radio frequency currents in it. The radio receiver extracts the information from the received waves. A practical radio transmitter mainly consists of the following parts: In higher frequency transmitters, in the UHF and microwave range, free running oscillators are unstable at
4453-486: The receiver, these pulses were sometimes directly recorded on paper tapes, but more common was audible reception. The pulses were audible as beeps in the receiver's earphones, which were translated back to text by an operator who knew Morse code. These spark-gap transmitters were used during the first three decades of radio (1887–1917), called the wireless telegraphy or "spark" era. Because they generated damped waves , spark transmitters were electrically "noisy". Their energy
SECTION 60
#17327978841704526-475: The same frequency will interfere with each other, causing garbled reception, so neither transmission may be received clearly. Interference with radio transmissions can not only have a large economic cost, it can be life-threatening (for example, in the case of interference with emergency communications or air traffic control ). For this reason, in most countries, use of transmitters is strictly controlled by law. Transmitters must be licensed by governments, under
4599-512: The transmitter usually must hold a government license, such as a general radiotelephone operator license , which is obtained by passing a test demonstrating adequate technical and legal knowledge of safe radio operation. Exceptions to the above regulations allow the unlicensed use of low-power short-range transmitters in consumer products such as cell phones , cordless telephones , wireless microphones , walkie-talkies , Wi-Fi and Bluetooth devices, garage door openers , and baby monitors . In
