1. MOSFET Mixer
The diagram to the right shows a single stage MOSFET tuned mixer. Depending on the frequency of operation, the gain will be from 10dB to 20dB -
Decoupling values are typical for operation on the HF bands.
AGC should not be applied to this type of circuit.
Oscillator injection should be 4v peak-
