MAX2837

2.3GHz to 2.7GHz Wireless

Broadband RF Transceiver

General Description

Features

● 2.3GHz to 2.7GHz Wideband Operation

The MAX2837 direct-conversion zero-IF RF transceiver

is designed specifically for 2.3GHz to 2.7GHz wireless

broadband systems. The MAX2837 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 synthe-

sizer, crystal oscillator, and baseband/control interface.

The device includes a fast-settling sigma-delta RF syn-

thesizer with smaller than 20Hz frequency steps and a

crystal oscillator, which allows the use of a low-cost crys-

tal in place of a TCXO. 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), crystal, RF switch, PA, and a small number of

passive components are needed to form a complete wire-

less broadband RF radio solution.

● Complete RF Transceiver, PA Driver, and Crystal

Oscillator

• 0dBm Linear OFDM Transmit Power

• -70dBr Tx Spectral Emission Mask

• 2.3dB Rx Noise Figure

• Tx/Rx I/Q Error and LO Leakage Detection

• 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

• 94dB Receive Gain-Control Range

• 60dB Analog RSSI Instantaneous

Dynamic Range

• 4-Wire SPI Digital Interface

• I/Q Analog Baseband Interface

• Digitally Tuned Crystal Oscillator

• On-Chip Digital Temperature Sensor Read-Out

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 specifica-

tions. The device supports up to 2048 FFT OFDM and

implements 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.
