MOSFET RF transistors are metal-oxide field effect transistors (MOSFETs) that are designed to handle high-power radio frequency (RF) signals from devices such as stereo amplifiers, radio transmitters, ...
An RF power amplifier is used to amplify radio frequency (RF) transmissions. A high power amplifier is used to amplify high power transmissions. An audio power amplifier or a power acoustic amplifier ...
A varicap tuned MOSFET RF amplifier followed, and then a local oscillator. Finally it became a fully-functional FM radio, with probably far better performance than most commercial radios.
