2. Rockwell Collins - Wikipedia

   en.wikipedia.org/wiki/Rockwell_Collins

   Within 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 ...

   This amplifier design improved, but did not solve, the problems of transcontinental telecommunication. [ 2 ] After years of work Black invented the negative feedback amplifier which uses negative feedback to reduce the gain of a high-gain, non-linear amplifier and makes it act as a low-gain, linear amplifier with much lower noise and distortion.
