CX74036 - IS-136 Receive RF IC for TDMA and AMPS Applications

General Description

Low Noise Amplifiers: The CX74036 contains two www.DataSheet4U.com independent LNAs for the cellular and PCS bands.

The gain of both LNAs can be switched off to a loss mode via one command 330 nH line interface.

Only one LNA is powered at any given time.

Key Features

  • Front-end to baseband in one IC Inphase and Quadrature (I/Q) demodulator 3 V supply operation Low current consumption LNA gain switch with current reduction IF LO synthesizer with Voltage Controlled Oscillator (VCO) (requires external tank).
  • 70 dB Variable Gain Amplifier (VGA) dynamic range.
  • Low Noise Figure (NF) and high 3rd order Input Intercept Point (IIP3) mixers.

www.DataSheet4U.com CX74036 IS-136 Receive RF IC for TDMA and AMPS Applications Conexant’s CX74036 receive RF IC is an advanced, highly integrated and high performance, triple-mode, dual-band IC for IS-136 compliant cellular radio applications and is designed in an advanced 28 GHz Ft BiCMOS process. In the 800 MHz cellular band, the CX74036 is designed to operate in both the Time Division Multiple Access (TDMA) mode and Advanced Mobile Phone System (AMPS) mode. In the 1900 MHz Personal Communications System (PCS) band, the device operates in the TDMA mode. The CX74036 embodies all the necessary functions for a radio receiver system except for the RF and Intermediate Frequency (IF) filters and RF Local Oscillator (LO) sources.
