Re: Identifying some microwave parts
The MCSL part is an X band free running swept source, varactor tuned. It comprises a grounded collector 2N3866 power oscillator driving a step recovery diode (SRD), followed by a waveguide filter. The frequency range is maybe 8 -10Ghz with a few mW out.
Not a lot of use for the amateur as its stands unless you rescue the SRD for your own multiplier or use the unit as an LO for a crude Spectrum Analyser??? Supply is -24v from memory but not sure what the varactor tuning input needed.
