This is 100 watt linear amplifier and may be built using two MRF309 transistors in push-pull, requiring only 16 watts drive from 420 to 450 MHz. The 100 watt linear amplifier operating from a 28 volt supply, 8 dB of power gain is achieved along with excellent practical performance featuring: maximum input SWR of 2:1, harmonic suppression more than-63 dB below 100 watts output, efficiency greater than 40%, circuit stability with a 3:1 collector mismatch at all phase angles.
