DESCRIPTION

GND(IQ)

The UPC2781GR is a Silicon MMIC IQ demodulator manu-

factured with the NESAT III™ silicon bipolar process. The IC

consists of an AGC amplifier, double balanced mixers, oscil-

lator, 90˚ phase shifter, and I&Q output buffer amps. The

device was specifically designed for DBS receivers and other

digital communication systems.
