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.

♦ Complete RF Transceiver, PA Driver, and  
Crystal Oscillator

Monolithic Low-Noise VCO with -39dBc  
Integrated Phase Noise  
Programmable Tx I/Q Lowpass  
Anti-Aliasing Filter  
Sigma-Delta Fractional-N PLL with  
20Hz Step Size  
45dB Tx Gain-Control Range  
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.
