    mosfet push pull rf amplifier

    Hi people,

    I'm trying to design a 1 Watt push pull amplifier using dual NPN RF MOSFET at 40MHz and a 24 Volt single supply. I'm not using any inductors or transformers. I'm not sure how to bias the MOSFET correctly. What type of biasing circuit should I be using ?

    Since I'm using dual NPN, does this mean I need a phase splitter or is there another option besides PNP?

    And since, I've got a single supply, does that mean I gotta operate the MOSFETs in Class A Push Pull?

    Thanks,

    Jeeves.

    Re: RF MOSFET Push Pull Amplifier

    Can anyone help with biasing the MOSFET push pull amplifier ?
