RMPA2263

The RMPA2263 Power Amplifier Module (PAM) is Fairchild's latest innovation in 50 Ohm 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 RMPA2263 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 more than 50% at 16 dBm 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. Further, the 4x4 x 1.5 mm LCC package is pin-compatible and a drop-in replacement for last generation 4x 4 mm PAMs widely used today, minimizing the design time to apply this performance-enhancing technology. The multi-stage GaAs Microwave Monolithic Integrated Circuit (MMIC) is manufactured using Fairchild RF's InGaP Heterojunction Bipolar Transistor (HBT) process.
