Answering the call for ultra-low DC power consumption and extended battery life in portable electronics, the RMPA0963 uses novel proprietary circuitry to dramatically reduce amplifier current at low to medium RF output power levels (< +16 dBm), where the handset most often operates. A simple two-state Vmode control is all that is needed to reduce operating current by m...
