The RFSP2020 power amplifier is a highperformance GaAs HBT IC designed for use in transmit applications in the 2.4-2.5 GHz frequency band. With a P1dB of 25 dBm, the device is ideal as a final stage for wireless LAN applications equiring high transmit linearity. Designed with advanced linearizing techniques, the device achieves a specific error vector magnitude (EVM) with lesser backoff than conventional PA designs.

The PA exhibits unparalleled linearity and efficiency for both 802.11b- and 802.11g-based WLAN systems. The RFSP2020 on-chip detector is perfect for systems where power sensing is necessary. The part operates off a single +3.3V supply.
