General Description

The RMPA2266 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 RMPA2266 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 reduce operating current by more than 60 at 16dBm output power, and quiescent current (Iccq) by as much as 70 compared to traditional power-saving methods. No additional circuitry, such as DC-to-DC converters, are required to achieve this remarkable improvement in amplifier

efficiency.
