W-CDMA/HSPA Band VIII Power Amplifier
Data Sheet
Description
The AJAV-5508 is a complete, high-performance power
amplifier for W-CDMA and HSPA wireless communica-
tions. Based on a unique, patented architecture, the AJAV-
5508 integrates circuitry for TX filtering, RF coupling,
power regulation, input and output matching and power
control. The PA is powered by a single connection to the
battery and is implemented in a standard CMOS process.
