Features
■ 40% WCDMA efficiency at +28dBm Pout
■ 20% WCDMA efficiency (58mA total current) at tm General Description The RMPA1766 Power Amplifier Module (PAM) is Fairchild’s latest innovation in 50Ω matched, surface mount modules targeting UMTS/WCDMA/HSDPA applications. Answering the call for ultra-low DC power consumption and extended battery life in portable electronics, the RMPA1766 uses novel proprietary circuitry to dramatically reduce amplifier current at low to medium RF output power levels (< +16dBm), where the handset most often operates. A simple two-state Vmode control is all that is needed to...

RMPA1759
manufacturer
Fairchild Semiconductor
Korean-PCS PowerEdge Power Amplifier Module
The RMPA1759 power amplifier module (PAM) is designed for Korean 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 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 InGaP Heterojunction Bipolar Transistor (HBT) process. Features • Single positive-supply operation and low power and shutdown modes • 38% 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 b...
