23cm 250watt
ON0EME is using 2 of these amplifiers parallel in their moon beacon.
Due to constant use in this beacon the hybrids burned out so i improved the output staged for new amplifiers with teflon.
3.5 watt in 250 watt out p1db at 28 volt 19amps 1296 mhz only. not menth for atv or continues use.
at 29 volt output power is around 290 - 310 watt p1db. and superlinear at this voltage to 250watt
above measurements have been confirmed by several buyers.
one buyer even tested with pulsed mode, power then was 400 watt at p6db.
i have done 440 watt atv tests myself at 30watt input but fets will die within 15 minutes.
normal usage should never exceed 300 watt for longlivity at low case temp.
requires some serious attention to the cooling, because housing is small, 10cm x 16cm.
contains copper base to spread heat..
price 500 euro. (improved version, with new batch of more expensive fets)
for 20 euro extra i will insert more 2 times more copper. 8cm x 10cm x 1cm instead of 10cm x 5cm x 0.8cm
comes with temperature overheat warning output and bias input.
with the 90 euro heatsink+1 blower setup it can do jt65 1 minute on / 1 minute off and ssb and cw.
with 2 blowers is 125 euro with grills

amp with copper enough for ssb:


amp with more copper for hotter enviroment or lower fanspeed:

a 2 blower setup and a 3rd empty blower case in between to prevent airhorn noise effect of the blower propellers.


flatmilled heatsink, also usable for the 150 watt.

13cm 8watt to 30 watt conversion

This amplifier was my first amplifier for amateur use.
it made 8 watt with 25mW.
later i got fets with higher amplification and more power so this version is outdated.
i made a kit that replaced the 2 endfets of this amp. with this kit in place it will do 30 watt with 28volt 3 amps.
