2.3GHz to 2.7GHz MIMO Wireless

Broadband RF Transceiver

MX2839AS

General Description

Features

The MAX2839AS direct conversion, zero-IF, RF transceiver

is designed specifically for 2.3GHz to 2.7GHz 802.16e

MIMO mobile WiMAX™ systems. The device incorpo-

rates one transmitter and two receivers, with > 40dB iso-

lation between each receiver. The MAX2839AS

completely integrates all circuitry required to implement

the RF transceiver function, providing RF to baseband

receive path, and baseband to RF transmit path, VCO,

frequency synthesizer, crystal oscillator, and base-

band/control interface. The device includes a fast-set-

tling sigma-delta RF synthesizer with smaller than 40Hz

frequency steps and a crystal oscillator that allows the

use of a low-cost crystal in place of a TCXO. The trans-

ceiver IC also integrates circuits for on-chip DC-offset

cancellation, I/Q error, and carrier leakage detection

circuits. An internal transmit to receive loopback mode

allows for receiver I/Q imbalance calibration. The local

oscillator I/Q quadrature phase error can be digitally

corrected in approximately 0.125° steps. 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 MAX2839AS completely eliminates the need for an

external SAW filter by implementing on-chip program-

mable monolithic filters for both the receiver and trans-

mitter, for all 2GHz and 802.16e profiles and WiBro. The

baseband filters along with the Rx and Tx signal paths

are optimized to meet the stringent noise figure and lin-

earity specifications. The device supports up to 2048

FFT OFDM and implements programmable channel fil-

ters for 3.5MHz to 20MHz RF channel bandwidths. The

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

IC is available in a small wafer-level package (WLP)

measuring 5.16mm x 3.66mm x 0.5mm.
