MAX2837

MAX2837 EVALUATION KIT AVAILABLE 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 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 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 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 wireless broadband RF radio solution. The MAX2837 completely eli...
