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.
i can make pcb's for any kind of power module.
for example mhw720 m57762 m67715 ra18h1213g
pcb only, 10 euro, with components 12.50 euro
kit with pc and case and components but with no powermodule 75 euro
i also make this with power sense and or wih mmic chamber for 1mw input
RA18H1213G ready build in case 160 euro, see foto.

1 watt in 100watt p1db out 28volt and 7 amps.
housing is 12cm x 6cm.
price is 175 euro.
only 1296 mhz version are available
all small amplifiers can have a circulator build in. this is 75 euro extra.
150 watt and is available in 2 versions. both 250 euro.
same ssb output as 8 x m57762 !
8 watt in 140-150 watt amp out.
frequency range 1240mhz - 1280mhz.
8 watt in 150 watt p1db out.
frequency range 1290mhz - 1310mhz.
28 volt 11 amps
N or sma connector input and N connector output.
13cm 25 / 90 watt
i have various amplifiers for 2320-2400Mhz.
1 stage amps upto 3 stage amps.
input power can vary from 1mw to 4watt.
output power varies from mw's to 100 watt.
for atv, 80mw-250mw in 100 watt out 250 euro, adjustable power.
3.5 watt in 90 watt out 150 euro
800mW in 25 watt out 125 euro
with intergrated circulator is 75 euro extra
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
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.
