The MC12002 is a double balanced analog mixer, including an input
amplifier feeding the mixer carrier port and a temperature compensated bias
regulator. The input circuits for both the amplifier and mixer are differential
amplifier circuits. The on-chip regulator provides all of the required biasing.
This circuit is designed for use as a balanced mixer in high-frequency
wide-band circuits. Other typical applications include suppressed carrier and
amplitude modulation, synchronous AM detection, FM detection, phase
detection, and frequency doubling, at frequencies up to UHF.
