MAX2830ETM+

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.

• Transceiver operates from 2.7V to 3.6V and power amplifier operates from 2.7V to 4.2V
• Operating temperature range from -40°C to 85°C
• Best in class transceiver performance and low power shutdown mode
• 62mA receiver current, 3.3dB Rx noise figure and -75dBm Rx sensitivity (54Mbps OFDM)
• 0.1dB/0.35° Rx I/Q gain/phase imbalance, 33dB RF and 62dB baseband gain control range
• 60dB range analogue RSSI per RF gain setting and fast Rx I/Q DC offset settling
• Supply current of 28mA (standby), 62mA (Rx mode) and 82mA (Tx mode) at TA = 25°C
• Greater than 40dB Tx sideband suppression without calibration
• Output power of 17.1dBm (output power adjusted to meet 5.6%EVM and spectral mask)
• No I/Q calibration is required
