    Here are a few photos of the new multiplier block i have been working on for my 134GHz system.

    This allows the input 33GHz to be on one side and the 134GHz output on the other, generally easier for mounting onto horn or at a dish feedpoint.
    It is based around a board from DB6NT, PCB no. 47 - 40/120 GHz Tripler / Mixer.

    Tx output 134.4GHz < 1mW likely. Using MA4E1310 Diode from DL2AM
    For Rx i use the MA4E1318 dual diode also from DL2AM, >10dB better sensitivity than 1310 diode.
