M/A-COM, a business unit of Tyco Electronics and a provider of wireless radio frequency (RF), microwave and millimeter-wave components, announced a new low cost RoHS compliant 2.4 GHz linear power amplifier for 802.11b/g Multiple-Input Multiple-Output (MIMO) WLAN applications that require high gain, high efficiency and small size. The MAAP-008015 amplifier provides 20 dBm of linear output power with EVM < 3.0 percent, maximizing system performance while maintaining low DC power consumption.
The MAAP-008015 is a three-stage power amplifier designed specifically for linear 802.11b/g applications and is available in a lead-free 3 mm 12-lead PQFN plastic package. The power amplifier features an integrated power detector for accurate power control and a separate power mode pin for current savings in the power shutdown mode state.
For 802.11g applications, the power amplifier is designed to generate 16 dBm of linear output power (OFDM, QAM-64, 54 Mbps) while drawing only 65 mA of current and maintaining an EVM of < 3.0 percent. For 802.11b applications, the device is designed to generate up to 20 dBm of linear output power while consuming only 100 mA of current. The MAAP-008015 has a typical linear gain of 31 dB at an operating voltage of 3.3 V. The MAAP-008015 is available from stock and is priced at $0.35 in quantities of 100K.
