General Description

The MAX2395 fully monolithic quasi-direct modulator IC is designed for use in WCDMA/UMTS transmitters. The quasi-direct modulation architecture reduces system cost, component count, and board space compared to transmitters using an IF SAW filter with IF VCO and IF synthesizer blocks.

Features

♦ 5 EVM for POUT = +6dBm

♦ 1920MHz to 1980MHz Operation

♦ +2.7V to +3.3V Single-Supply Operation

♦ +6dBm Output Power at 72mA

♦ 81dB Minimum Automatic Gain-Control (AGC) Range

♦ Automatic ICC Throttle Back for Optimal Power Consumption

♦ No IF SAW Filter Necessary

♦ On-Chip RF PLL, with Fully Monolithic VCO

♦ Ultra-Low External Component Count

Applications

    WCDMA Phones

    UMTS/EDGE Phones

    W-TDD Phones
