RMPA1963 Overview
The RMPA1963 Power Amplifier Module (PAM) is Fairchild’s latest innovation in 50 Ohm matched, surface mount modules targeting US-PCS CDMA/WCDMA/HSDPA and Wireless Local Loop (WLL) applications. Answering the call for ultra-low DC power consumption and extended battery life in portable electronics, the RMPA1963 uses novel proprietary circuitry to dramatically reduce amplifier current at low to medium RF output power...
