Detailed description

The MAX2830 is a single-chip, single-band, dual-mode™ direct-conversion transceiver designed for 2.4GHz 802.11b/g (OFDM and CCK) WLAN applications. The device integrates all the circuitry required to implement complete RF transceiver functionality: PA, T/R switch, antenna diversity switch, LNA, 50Ω matching components, sigma-delta fractional synthesizer, crystal oscillator, and unique I/Q amplitude and phase-error calibration circuit. The device also eliminates the need for external SAW filters by implementing on-chip monolithic filters for both the receiver and transmitter. The baseband Tx and Rx filters are optimized to meet the 802.11g IEEE standard. With an additional RF filter and a few passive components, a complete 802.11b/g WLAN RF front-end solution can be formed that provides high performance in a small size and low cost.
