2.3GHz to 2.7GHz Wireless

Broadband RF Transceiver

MAX2837

General Description

Features

The MAX2837 direct-conversion zero-IF RF transceiver

is designed specifically for 2.3GHz to 2.7GHz wireless

broadband systems. The MAX2837 completely inte-

grates all circuitry required to implement the RF trans-

ceiver function, providing RF-to-baseband receive path;

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

synthesizer, crystal oscillator, and baseband/control

interface. The device includes a fast-settling sigma-

delta RF synthesizer with smaller than 20Hz frequency

steps and a crystal oscillator, which allows the use of a

low-cost crystal in place of a TCXO. The transceiver IC

also integrates circuits for on-chip DC offset cancella-

tion, I/Q error, and carrier-leakage detection circuits.

Only an RF bandpass filter (BPF), crystal, RF switch,

PA, and a small number of passive components are

needed to form a complete wireless broadband RF

radio solution.

The MAX2837 completely eliminates the need for an

external SAW filter by implementing on-chip monolithic

filters for both the receiver and transmitter. The baseband

filters along with the Rx and Tx signal paths are optimized

to meet stringent noise figure and linearity specifications.

The device supports up to 2048 FFT OFDM and imple-

ments programmable channel filters for 1.75MHz to

28MHz RF channel bandwidths. The transceiver requires

only 2µs Tx-Rx switching time, which includes frequency

transient settling. The IC is available in a small, 48-pin thin

QFN package measuring only 6mm x 6mm x 0.8mm.
