DESCRIPTION
The UPC2766GR Silicon MMIC Wideband IQ Demodulator
was manufactured with the NESAT III MMIC process. The
NESAT III process produces transistors with fT approaching
20 GHz. The device was designed specifically for digital video
and data receivers. The IC consists of a wide band RF
amplifier, Gain Control amplifier, dual balanced mixers, LO
buffers, and I & Q output buffer amplifiers.
NEC's stringent quality assurance and test procedures en-
sure the highest reliability and performance.
