µPC3205GR
IQ DEMODULATOR FOR DIGITAL VIDEO/DATA RECEIVER
DESCRIPTION
The µPC3205GR is Silicon monolithic IC designed for use as IQ demodulator in digital communication systems.
This IC consists of AGC amplifier, dual balanced mixers (DBM), oscillator, quadrature phase shifter and I & Q output
buffer amplifiers.
The package is 20-pin SSOP (shrink small outline package) suitable for high-density surface mount.
FEATURES
• On chip quadrature (90°) phase shifter
• IQ phase and amplitude balance
Amplitude Balance : ±0.5 dB
Phase Balance : ±2.0 degree
• Low distortion
IM3 : 56 dBc (@0.708 VP-P/tone)
• Supply Voltage
VCC : 5 V
• Packaged in 20-pin SSOP suitable for high-density surface mount
