2. Linear amplifier - Wikipedia

   en.wikipedia.org/wiki/Linear_amplifier

   A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier, some of which have output power measured in kilowatts, and are used in amateur radio. Other types of linear amplifier are used in ...

3. Class-D amplifier - Wikipedia

   en.wikipedia.org/wiki/Class-D_amplifier

   The first class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964. However, it had an output power of only 2.5 watts. The Sinclair X-20 in 1966 produced 20 watts but suffered from ...

4. 807 (vacuum tube) - Wikipedia

   en.wikipedia.org/wiki/807_(vacuum_tube)

   The 807 is fully rated to 60 MHz, derated to 55% at 125 MHz in Class C, Plate-modulated operation, thus they were popular with amateur radio operators (radio hams). In this application a single 807 could be run in class-C as an oscillator or amplifier which could be keyed on and off to transmit Morse Code in CW mode.

5. Yaesu FT-101 - Wikipedia

   en.wikipedia.org/wiki/Yaesu_FT-101

   Yaesu FT-101 is a model line of modular amateur radio transceivers, built by the Yaesu Corporation in Japan during the 1970s and 1980s. FT-101 is a set that combines a solid state transmitter, receiver and a tube final amplifier. Its solid state features offer high-performance, low-current characteristics and its tube amplifier provides an ...

6. Amateur radio - Wikipedia

   en.wikipedia.org/wiki/Amateur_radio

   Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. [ 1] The term "amateur" is used to specify "a duly authorized person interested in ...

7. RF power amplifier - Wikipedia

   en.wikipedia.org/wiki/RF_power_amplifier

   A radio-frequency power amplifier ( RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [ 1] Typically, RF power amplifiers are used in the final stage of a radio transmitter, their output driving the antenna. Design goals often include gain, power output ...
