Maxim has introduced the MAX2830 single-chip, direct-conversion, ultra-low-power 802.11g/b RF transceiver with integrated power amplifier (PA), Rx/Tx/antenna diversity switches, and crystal oscillator circuitry. The low cost and small size of this highly integrated transceiver make it ideal for Wi-Fi, PDA, VoIP, and cellular handset applications. It also integrates digitally controlled crystal oscillator (DCXO) circuitry to implement the reference oscillator function, thus allowing the use of small, low-cost, low-power crystals.
The transceiver operates from a 2,7 V to 3,6 V supply, and the PA operates from 2,7 V to 4,2 V. The receiver consumes 62 mA of current in receive mode, while achieving a low noise figure of 3,3 dB, thus enabling receive sensitivity of
-75 dBm (64QAM OFDM) without an external LNA. Additionally, the transmitter and PA deliver linear transmit power of +17 dBm (64QAM OFDM) after the switch. A 20 μA low-power shutdown mode is available to further save power.
