µPC2766GR/GS
WIDE BAND IQ DEMODULATOR FOR DIGITAL VIDEO/DATA RECEIVER
DESCRIPTION
The µPC2766GR/GS is a Silicon monolithic IC designed for use as IQ demodulator in wide dynamic range
compressed video or spread spectrum receivers. This IC consists of a wide band RF amplifier, gain control amplifier,
dual balanced mixers (DBM), Lo buffers, and I & Q output buffer amplifiers.
The package is 20 pin SSOP (shrink small outline package: µPC2766GR) or 20 pin SOP (µPC2766GS) suitable
for high-density surface mount.
FEATURES
• Broadband operation
RF & LO up to 1 000 MHz
IF (IQ) up to 200 MHz
• Wideband IQ phase and amplitude balance
Amplitude balance ±0.3 dB (TYP.)
Phase balance
±0.3 degree (TYP.)
• AGC dynamic range
45 dB
• Low distortion; IM3
30 dBc
• Supply Voltage
5V
• Packaged in 20 pin SSOP or 20 pin SOP suitable for high-density surface mount
