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 high-
performance 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.
