The RFSP5022 power amplifier is a high-
performance GaAs HBT IC designed for use in
transmit applications in the 5.15-5.85 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. The
part demonstrates very low error vector magnitude
(EVM) at the full 54 Mbps data rate for 802.11a.
The input of the PA is matched to 50 ohms and the
output can be easily matched for optimum linearity
and power performance at the desired frequency of
operation between 5.15 and 5.85 GHz. The part
operates off a single +3.3V supply.
