I have related question. Assuming we have FET oscillator (5GHz). DRO/microstrip/series/parallel/etc.. configuration.
If received RF is applied to LO(drain) output port of oscillator, can we expect IF mixing product on drain?
If received RF is applied to gate of oscillator's FET, similar question.
To clarify my question, here is setup configuration:
1) DRO 5000 MHz
2) FET coupled to DRO
3) receiving antenna connected drain (or gate) of FET
incoming 5001 MHz is applied to receiving antenna, and then applied to drain or gate of FET oscillator.
- Would we see any mixing? I mean IF= 1 MHz
- Would not frequency of oscillator be "pulled" to 5001 MHz. As i understand it is kind of injected signal, so in theory 5000 MHz oscillator's frequency could float to a new point F=5001MHz...
