2.3GHz to 2.7GHz Wireless
Broadband RF Transceiver
General Description
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.
