Description
The W3030 is a monolithic integrated circuit that provides most of the receive path functions required to meet the IS-136 (and IS-54) standard. The W3030 converts FM or digitally modulated IF carriers up to 200 MHz and provides required IF gain and separate baseband detectors for the two modulation modes.

FEATUREs
■ Proven double conversion architecture:
    - First IF capability: 10 MHz to over 1000 MHz
    - Second IF capability: 0.2 MHz to 2.0 MHz
■ Dual second IF amplifiers and demodulators:
    - Analog-mode limiting amplifier and FM quadrature detector
    - Digital-mode linear AGC amplifiers with dual-mixer I & Q quadrature demodulator
■ Accurate, onboard local oscillator phase splitter for digital quadrature demodulator
■ Four enable/powerdown modes, selectable from two digital control pins, allow operation with minimal supply current
■ Low supply current
■ Analog received signal strength indicator (RSSI) available
■ Analog AGC for digital-mode IF amplifiers
■ Over 100 dB combined voltage gain

APPLICATIONs
■ IS-136 (North American dual-mode) cellular radio portable and mobile terminals
■ Cellular radio base stations
■ Digital satellite communications
■ Multisymbol signaling receivers
