Device
General Description
The RMPA1765 power amplifier module (PAM) is designed for
Korean CDMA, CDMA2000-1X and WCDMA 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’s InGaP Heterojunction Bipolar
Transistor (HBT) process.
