Re: 10GHz Capable Sig Gen WB SG 1

Hi All,

Thanks for the suggestions, the synth followed by a tripler sounds like a good idea and I'm not too worried if the output is not particularly clean as I only intend to use it for setting up the RX at this stage. Like you say it should be good enough to get me going.

I did something similar, using an LMX2541 synth as the source and an under-run ERA-1 as the tripler.   The filter was an evanescent design built in WG20,  then the 10GHz amplified in a surplus module up to +22dBm for a personal beacon source.

JT4G modulation was added using direct programming of the synthesizer.

I also needed a signal source to get going on 10 GHz. My solution was to use a tripler after an ADF 4350 synth module. The tripler I chose was the RMK-3-153 from MCL. It works very well over quite a wide band and gives around -10dBm out for + 11 dBm in, and 2Fin and 4Fin are both respectably low. I used one of the ERA series amps with suitable input attenuation to raise the level of the synth up to +11 dBm. I used a printed HPF at the output to attenuate the drive signal.

The multiplied output from the synth is not particularly clean, but it was good enough to get me going.
