40 watt on 13cm atv amplifier project

1w in, 40 watt out. 28 volt 3 ampere

due to very low demand for this amp i never updated this page.
in the beginning of my amplifier work i used wrongly calibrated attenuators which led to wrong measurements.
all this has all been corrected for all my amps except for this amp.
but recently i made a new pcb with which 35watt p1db is possible at 32 volt and 45 watt saturated.
when i first designed it i was never interested in ssb work and so all the measurements where done in saturation.

the amp is 125 euro version mounted inside an alu box.
(this is dirt cheap, sometimes during building this amp i lose a fet, resulting in selling the amp without a penny of profit)
