This circuit is a broadband 4 quadrant analog mixer. It is expected to perform analog multiplication of two input signals from 5Mhz to 300MHz with an output frequency of 1Hz – 100MHz. This circuit was built in order to monitor only the differential change in frequencies of two oscillator circuits operated by crystal microbalances at resonance.
