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, and television monitors. They are turned on and off by input voltages and function as. 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, and television monitors. They are turned on and off by input voltages and function as miniature electronic switches.


The Infineon MOSFETs include several sub-categories, depending on whether the biasing resistor network at the RF input port is fully integrated (full-biased), partly integrated (semi-biased) or not at all integrated (non-biased). Mainstream TV tuners are either a semi-biased or an intelligent-switching concept, while FM radio tuners mainly use single non-biased or single full-biased MOSFETs.

As a key component in the tuner pre-stage circuit, Infineon RF MOSFET features:
