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 ApplicationNote AN531 for additional design information. • Excellent Carrier Suppression –65 dB typ @ 0.5 MHz Excellent Carrier Suppression –50 dB typ @ 10 MHz • Adjustable Gain and Signal Handling
