M/A-COM introduces the new MAAPSS0075 RoHS-compliant 2.4 GHz linear PA for 802.11b/g WLAN applications. The MAAPSS0075 is a three-stage power amplifier designed for linear 802.11b/g applications, which is available in a lead-free 3 mm 12-lead PQFN plastic package. The power amplifier features an integrated power detector for power control and a separate power mode pin for current savings in a power shutdown mode state. For 802.11g applications, the PA generates 19 dBm of linear output power (OFDM, QAM-64, 54 Mb/s) while drawing 160 mA of current and maintaining an EVM of < 3.5%. For 802.11b applications, the PA generates up to 23 dBm of linear output power using 250 mA of current. The MAAPSS0075 has a typical linear gain of 32 dB with an operating voltage of 3.3 V.
