    I am trying to design a push pull class AB power amplifier (100W) to function at 300 MHz but cannot use a transformer in my design. Thus, I need complementary transistors for the push pull function. Are there any transistors that match this specification? Is there any other way to design a push pull amplifier without a transformer of complementery transistors? Thanks.

    At that kind of power level for that frequency, you're probably looking at a range of $70 to $300 per transistor or MOSFET.

    Have a look around on NXP Semiconductors' site.

    I have searched but have been unable to find any complementary pairs of RF Power transistors which makes me wonder whether they even exist. Is there any way to construct a push pull amplifier without a transformer or complementary pairs?

    Hello,

    I moved the thread over here as it is RF related.

    The use of class AB amplifiers is not common for RF amplifiers.
    On this linkpage of the EDUCYPEDIA you will find some links on RF amplifiers:
