General Description
The RMPA1959 power amplifier module (PAM) is designed for CDMA and CDMA2000-1X personal communications system (PCS) applications. The 2 stage PAM is internally matched to 50Ω to minimize the use of external components and features advanced DC power management to reduce current consumption during peak phone usage. High power-added efficiency and excellent linearity are achieved using our InGaP Heterojunction Bipolar Transistor (HBT) technology.

Features
• Single positive-supply operation and low power and shutdown modes
• 39% CDMA efficiency at +28dBm average output power
• Compact 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
