Late '70's vintage likely Military, probably airborne, VHF power
amplifier
assembly. It consists of 7 almost identical amplifier assemblies
clustered around a
central housing that has splitter combiner networks which are plugged
onto each end with a bunch of SMB connectors. There are TNC's for the
main in's & outs. I think it was originally configured as one amp,
driving two, driving four boards. The complete assembly measures 7.5" x
5"
x 3.5" overall -- the individual RF amp boards are 4.5" by 2". The
outer covers
are mostly missing. Each amplifier is a push pull design -- they appear
to be
50 ohm in & out impedance with either PT6747 or PT6702 TRW transistors.
I would
guess this unit operates on 28VDC. I don't know what frequency range it
covers nor the power level though, just guessing, it probably puts out at
least 100W. And there is no manufacturer name -- probably went with
the outer cover. Six of the stages are marked OK and one, the input
stage I think, is marked NO Good. The individual amps have integral heat
sink plates so, they could be removed from the assembly and used
separately. Think of it as 7 amplifier boards @ $10 ea --
Bare PCB's would cost as much! -- $70 May be seen at:
