Linear power amplifier features high gain, efficiency

M/A-COM has introduced the MAAPSS0075 RoHS-compliant 2.4 GHz linear power amplifier (PA) for 802.11b/g WLAN applications. The amplifier is suitable for installations that require high gain, high efficiency, and small size at a cost-effective price level.

The three-stage power amplifier is designed specifically for linear 802.11b/g applications. The power amplifier features an integrated power detector for accurate power control and a separate power mode pin for current savings in a power shutdown mode state. The amplifier achieves 19 dBm linear output power with an EVM of less than 3.5%, which maximizes system performance while maintaining low DC power consumption.

For 802.11g applications, the PA generates 19 dBm of linear output power (OFDM, QAM-64, 54Mbps) while drawing 160 mA of current and maintaining an EVM of less than 3.5%. For 802.11b applications, the PA generates up to 23 dBm of linear output power using only 250 mA of current. The amplifier has a typical linear gain of 32 dB with an operating voltage of 3.3 V.

The MAAPSS0075 is available from stock and is priced at $0.40 in quantities of 100,000. It is available in a lead-free 3-mm 12-lead PQFN plastic package.
