Re: 134 GHz frequency allocation

Roger Ray

Hi Bill,

The way most of us get to 134GHz. Is Elcom synthesiser on 11.2GHz, a Broadern module (X3 and Amp) giving 33.6GHz into the mixer. With the same for LO, 11.23666 x3 to 33.71 (134.84), giving 440MHz IF.
Although fine for TX the Broadern is a bit noisy as LO, so for >10km range I use a separate X3/amp in the RX LO chain.

Broadern modules are still on ebay, although the supply of 11.2-12GHz Elcom synthesisers seams to have dried up.
