Korean-PCS Power Edge™ Power Amplifier Module
General Description
The RMPA1759 power amplifier module (PAM) is designed for Korean CDMA and CDMA2000-1X personal munications system (PCS) applications. The 2 stage PAM is internally matched to 50Ω to minimize the use of external ponents 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 our In Ga P Heterojunction Bipolar Transistor (HBT) process.
Features
- Single positive-supply operation and low power and shutdown modes
- 38% CDMA efficiency at +28d Bm average output power
- pact LCC package- 4.0 x 4.0 x 1.5 mm with industry standard pinout
- Internally matched to 50Ω and DC blocked RF input/ output.
- Meets CDMA2000-1XRTT performance requirements
