High Efficiency Linear Power Amplifier Designed for WiFi and WiMAX Applications from RFMD

RF
Micro Devices, Inc. introduced the RF5602 high-power, high-efficiency
and high-linearity power amplifier (PA). The RF5602 is a 2GHz linear PA
designed for medium power applications including consumer premises
equipment (CPE) and access point (AP) applications for WiFi and WiMAX.

Manufactured using RFMD's advanced Indium Gallium Phosphide
(InGaP) Heterojunction Bipolar Transistor (HBT) semiconductor process
technology, the RF5602 is optimized for use as the final RF amplifier
in 802.16 e/d and 802.11 b/g/n applications. The RF5602 is also
applicable for 2.4 GHz ISM band applications, PCS communications
systems, and WiBro 2.3 GHz – 2.4 GHz applications. The RF5602 provides
strong linearity and delivers world-class error vector magnitude (EVM)
performance. — 2% EVM at 26 dBm output power, 5.0V — 2% EVM at 25 dBm
output power, 4.2V — 3% EVM at 23.5 dBm output power, 3.3V Additional
technical features include: — 3.3 to 5 V Supply Operation —
Integrated input power detector on die — 32 dB to 34 dB small signal
gain.
