Wireless Broadband RF Transceiver
General Description
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.
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.
