RF OUT/ VCC3
The RFSP5022 power amplifier is a highperformance Ga As HBT IC designed for use in transmit applications in the 5.15-5.85 GHz frequency band. With a P1d B of 25 d Bm, 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.
