Product Description

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.
