General Description

The RMPA1966 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 RMPA1966 uses novel proprietary circuitry to dramatically reduce amplifier current at low to medium RF output power levels (
