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

  • Best-in-class noise figure and gain 
  • Excellent cross-modulation 
  • ESD robustness protected via an on-chip gate protection diode 
  • 5th generation MOSFETs such as BF5030W and BG5120K fulfill the stringent technical requirement from the digital tuners and also support low-power 3V designs
  • Automotive quality (AEC Q101 qualified) 
  • RoHS compliant
