3.3GHz to 3.9GHz

Wireless Broadband RF Transceiver

MAX238

General Description

Features

♦ 3.3GHz to 3.9GHz Wide-Band Operation

The MAX2838 direct-conversion, zero-IF, RF transceiv-

er is designed specifically for 3.3GHz to 3.9GHz wire-

less broadband systems. The MAX2838 completely

integrates all circuitry required to implement the RF

transceiver function, providing RF-to-baseband receive

path, baseband-to-RF transmit path, VCO, frequency

synthesizer, and baseband/control interface. The

device includes a fast-settling sigma-delta RF synthe-

sizer with smaller than 29Hz frequency steps. The

MAX2838 supports 2Tx, 2Rx MIMO applications with a

master device providing coherent LO to the slave

device. The transceiver IC also integrates circuits for

on-chip DC-offset cancellation, I/Q error, and carrier-

leakage detection circuits. Only an RF bandpass filter

(BPF), TCXO, RF switch, PA, and a small number of

passive components are needed to form a complete

wireless broadband RF radio solution.

♦ Master-Slave Modes with Coherent LO for MIMO

♦ Complete RF Transceiver, and PA Driver

The MAX2838 completely eliminates the need for an

external SAW filter by implementing on-chip monolithic

filters for both the receiver and transmitter. The base-

band filters along with the Rx and Tx signal paths are

optimized to meet the stringent noise figure and lineari-

ty specifications. The device supports up to 2048-FFT

OFDM and implements programmable channel filters

for 1.5MHz to 28MHz RF channel bandwidths. The

transceiver requires only 2µs Tx-Rx switching time. The

IC is available in a small 48-pin thin QFN package mea-

suring only 6mm x 6mm x 0.8mm.
