Balanced Modulators/
Demodulators
These devices were designed for use where the output voltage is a
product of an input voltage (signal) and a switching function (carrier). Typical
applications include suppressed carrier and amplitude modulation,
synchronous detection, FM detection, phase detection, and chopper
applications. See Motorola Application Note AN531 for additional design
information.
