This is my 1kw Mosfet Rf Amplifier. The MosFets are IRF 450 . They have an "on resistance" of 0.31 Ohms , will dissipate about 190W each. Vdss Drain Source Voltage 500 , Id Continuous Drain Current 14 A , Ciss input Capacitance 2000pF,Output Capacitance 300pF I have used them in my base station and they produce a good 1000w from 70V on 80 , 600w on 160 and 40 M . see . . . schematic
