Details:
4 amps, a couple of fans and load. Up to 860 MHz.
Amplifier assembly has all temperature and bias circuits on a separate circuit board the outside of main RF area. For offer is a Comark uhf tv amplifier board with original heat sink, cover and all cables.
A separate ribbon wire is attached to monitor voltage s but does not need be or connected operate amplifier. This was part of a tv transmitter that disassembled at some time in the past. Amplifier is x12' x 2 high and will need to have a means of supplying air the heat-sink for continuous tv operation, Sb or intermittent FM use be analyzed heat issues.
The assembly uses 4 st sd1490-1 transistors rated for 25 watts out each from 470mhz. The was swept and it looks like will work fine in 440 ham band.
Add a 24 volt power supply good for 10. Bias circuits have separate controls for each active device plus all inputs and outputs are split coupled with hybrid couplets stable operation.
