Doubly Balanced Mixer
Phase Detection and FM Detection
The MC1 596/MC 1496 mav be used as a doublv balanced
The MCI 596/MC 1496 will function as a phase detector. High-

The local oscillator signal is introduced at the carrier input
port with a recommended amplitude of 100 mV(rms).

output which is a function of the phase difference$:m~~~the

The MCI 596/MC1496 will operate as a frequencv doubler bv
introducing the same frequencv at both input ports.
