MAX2830

EVALUATION KIT AVAILABLE AVAILABLE MAX2830 2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA, and Rx/Tx/Antenna Diversity Switch General Description The MAX2830 direct conversion, zero-IF, RF transceiver is designed specifically for 2.4GHz to 2.5GHz 802.11g/b WLAN applications. The MAX2830 completely integrates all circuitry required to implement the RF transceiver function, providing an RF power amplifier (PA), an Rx/Tx and antenna diversity switch, RF-to-baseband receive path, baseband-to-RF transmit path, voltage-controlled oscillator (VCO), frequency synthesizer, crystal oscillator, and baseband/control interface. The MAX2830 includes a fast-settling sigma-delta RF synthesizer with smaller than 20Hz frequency steps and a digitally tuned crystal oscillator allowing use of a low-cost crystal. No I/Q calibration is required; however, the device also integrates on-chip DC-offset cancellation and I/Q errors and carrier leakage-detection circuits for improved performance. Only an RF band...
