General Description

The RMPA1765 power amplifier module (PAM) is designed for Korean CDMA, CDMA2000-1X, WCDMA, and HSDPA personal communications system (PCS) applications. The 2 stage PAM is internally 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’s InGaP Heterojunction Bipolar Transistor (HBT) process.
