Preliminary RFSP2010
2.4–2.5 GHz Power Amplifier
Applications
802.11b/g WLAN 2.4 GHz ISM band wireless equipment
Product Description
The RFSP2010 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 requiring high transmit linearity. Designed with propriety linearizing techniques, the part is operable closer to P-1dB, which enables the device to achieve a specific error vector magnitude (EVM) with less backoff. The PA exhibits unparalleled linearity and efficiency for both 802.11b- and 802.11g-based WLAN systems. The part operates off a single +3.3V supply.
