47 GHz Part 1.....

This transverter is built mainly from surplus components.  It is a fixed frequency TX, tunable RX down converter.

The bottom half of the transverter is the TX chain.  A microwave brick oscillator running at 15GHz feeds an amplifier (blue rectangle in the middle).  The LO is attenuated and fed to the amp which is keyed on/off for CW.  The output of the amp feeds a 3x multiplier that has a claimed gain of 10 dBm out!  This output feeds an isolator and a manual waveguide switch (WR28) for T/R.  The output is a small test horn.

The upper part of the transverter is a Phillips 39ghz down converter which is capable of downconverting the 47 GHz signal with an IF of 10.368 GHz.  This downconverter feeds a 10G post amp which then would
be connected to a 10GHz transverter/2nd IF.

The front panel has a manual T/R switch to apply voltage to either the RX or TX chain.  A spot
button is provided that will apply power to the TX chain AND RX chain to allow finding the transmit signal while tuning the IF.  This transmitter is CW only

Beneath the chassis contains two brick oscillators for the RX and TX chain:

This transverter requires 12v and -20v (positive ground).  It is somewhat portable but
does require an outboard 10GHz rig for the 2nd IF.
My goal is to build a more optimized transverter - this unit will still be used as a back up
and as a test platform.
