The MAX2830ETM+ is a 2.4GHz to 2.5GHz, 802.11g/b RF transceiver, power amplifier (PA) and Rx/Tx/antenna diversity switch in 48 pin TQFN package. This 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 RF transceiver function providing an RF power amplifier (PA), Rx/Tx, antenna diversity switch, RF to baseband receive path, baseband to RF transmit path, VCO, frequency synthesizer, crystal oscillator and baseband/control interface. It includes fast settling sigma delta RF synthesizer with smaller than 20Hz frequency steps and digitally tuned crystal oscillator allowing use of low cost crystal. The MAX2830 completely eliminates the need for an external SAW filter by implementing on-chip monolithic filters for both receiver and transmitter. The baseband filters are optimized to meet IEEE 802.11g standard and turbo modes up to 40MHz channel bandwidth.
