    A 50W VHF(110 to 150MHz) Amplifier

    It's mentioned in the first post. I need a 50W power transistor for CW AM modulation in frequency band of 110 to 150MHz. Yes, you're right. I need exactly a transistor for working in CW mode. - - - Updated - - - Dear, You're right. But I need a transistor that has the push-pull or any other...

    A 50W VHF(110 to 150MHz) Amplifier

    thank you But I prefer not to use a push-pull transistors and circuits because of their high power dissipation! Actually I need class AB, C or D amplifier with efficiency of more that 65%. Indeed, both of two transistors that you've introduced, have output power of about 13W and its not enough...
