General Description

The RMPA1967 power amplifier module (PAM) is designed for

CDMA, CDMA2000-1X, WCDMA and HSDPA personal commu-

nications system (PCS) applications. The 2-stage PAM is inter-

nally matched to 50 Ohms to minimize the use of external

components and features a low-power mode to reduce standby

current and DC power consumption during peak phone usage.

High power-added efficiency and excellent linearity are

achieved using Fairchild RF鈥檚 InGaP Heterojunction Bipolar

Transistor (HBT) process.
