EVALUATION KIT AVAILABLE MAX2830 2.4GHz to 2.5GHz 802.11g/b RF Transceiver, PA, and Rx/Tx/Antenna Diversity Switch General Description Features The MAX2830 direct conversion, zero-IF, RF transceiver 2.4GHz to 2.5GHz ISM Band Operation is designed specifically for 2.4GHz to 2.5GHz 802.11g/b IEEE 802.11g/b Compatible (54Mbps OFDM and WLAN applications. The MAX2830 completely integrates 11Mbps CCK) all circuitry required to implement the RF transceiver Complete RF Transceiver, PA, Rx/Tx and Antenna function, providing an RF power amplifier (PA), an Rx/Tx and antenna diversity switch, RF-to-baseband receive Diversity Switch, and Crystal Oscillator path, baseband-to-RF transmit path, voltage-controlled Best-in-Class Transceiver Performance oscillator (VCO), frequency synthesizer, crystal oscillator, 62mA Receiver Current and baseband/control interface. The MAX2830 includes 3.3dB Rx Noise Figure a fast-settling sigma-delta RF synthesizer with smaller -75dBm Rx Sensitivity (54Mbps OFDM) than 20Hz frequency steps and a digitally tuned crystal No I/Q Calibration Required oscillator allowing use of a low-cost crystal. No I/Q cali- 0.1dB/0.35 Rx I/Q Gain/Phase Imbalance bration is required however, the device also integrates 33dB RF and 62dB Baseband Gain Control on-chip DC-offset cancellation and I/Q errors and carrier Range leakage-detection circuits for improved performance. 60dB Range Analog RSSI per RF Gain Setting Only an RF bandpass filter (BPF), crystal, a pair of Fast Rx I/Q DC-Offset Settling baluns, and a small number of passive components are Programmable Baseband Lowpass Filter needed to form a complete 802.11g/b WLAN RF front- 20-Bit Sigma-Delta Fractional-N PLL with end solution. < 20Hz Step Size The MAX2830 completely eliminates the need for an Digitally Tuned Crystal Oscillator external SAW filter by implementing on-chip monolithic fil- +17.1dBm Transmit Power (5.6% EVM with ters for both the receiver and transmitter. The baseband 54Mbps OFDM) filters are optimized to meet the IEEE 802.11g standard 31dB Tx Gain Control Range and proprietary turbo modes up to 40MHz channel band- Integrated Power Detector width. These devices are suitable for the full range of Fully Integrated RF Input and Output 802.11g OFDM data rates (6Mbps to 54Mbps) and Matching and DC Blocking 802.11b QPSK and CCK data rates (1Mbps to 11Mbps). Serial or Parallel Gain-Control Interface The ICs are available in a small, 48-pin TQFN package > 40dB Tx Sideband Suppression Without measuring only 7mm x 7mm x 0.8mm.
