The MAX2831/MAX2832 direct conversion, zero-IF, RF transceivers are designed specifically for 2.4GHz to 2.5GHz 802.11g/b WLAN applications. The MAX2831 completely integrates all circuitry required to implement the RF transceiver function, providing an RF power amplifier (PA), RF-to-baseband receive path, baseband-to-RF transmit path, VCO, frequency synthesizer, crystal oscillator, and baseband/control interface. The MAX2832 integrates the same functional blocks except for the PA. Both devices include 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. The devices also integrate on-chip DC-offset cancellation and I/Q errors and carrier leakage-detection circuits. Only an RF bandpass filter (BPF), crystal, RF switch, and a small number of passive components are needed to form a complete 802.11g/b WLAN RF front-end solution.

The MAX2831/MAX2832 completely eliminate the need for an external SAW filter by implementing on-chip monolithic filters for both the receiver and transmitter. The baseband filters are optimized to meet the IEEE® 802.11g standard and proprietary turbo modes up to 40MHz channel bandwidth. These devices are suitable for the full range of 802.11g OFDM data rates (6Mbps to 54Mbps) and 802.11b QPSK and CCK data rates (1Mbps to 11Mbps). The ICs are available in a small, 48-pin TQFN package measuring only 7mm x 7mm x 0.8mm.

Applications

  • General 2.4GHz ISM Radios
  • Wi-Fi, PDA, VoIP, and Cellular Handsets
  • Wireless Speakers and Headphones

Product Detail

The MAX2831 evaluation kit (EV kit) simplifies testing of the MAX2831 receive and transmit performance in 802.11g/b applications operating in the 2.4GHz to 2.5GHz ISM band. The EV kit provides 50Ω SMA connectors for all RF and baseband inputs and outputs. Differential-to-single-ended and single-ended-to-differential line drivers are provided to convert the differential I/Q baseband inputs and outputs to single ended.

Applications

  • General 2.4GHz ISM Radios
  • Wi-Fi, PDA, VoIP, and Cellular Handsets
  • Wireless Speakers and Headphones
