Meets CDMA2000-1XRTT/WCDMA performance require-
ments
General Description
The RMPA1765 power ampli鏗乪r 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 ef鏗乧iency and excellent linearity are
achieved using Fairchild RF鈥檚 InGaP Heterojunction Bipolar
Transistor (HBT) process.
