RMPA2263 Datasheet Wcdma Power Amplifier Module

Manufacturer: Fairchild (now onsemi)

Overview: RMPA2263 PRELIMINARY May 2005 RMPA2263 i-Lo™ WCDMA Power Amplifier Module 1920–1980.

General Description

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.

Key Features

  • 40% WCDMA efficiency at +28 dBm Pout.
  • 14% WCDMA efficiency (85 mA total current) at +16 dBm Pout.
  • Linear operation in low-power mode up to +19 dBm.
  • Low quiescent current (Iccq): 25 mA in low-power mode.
  • Meets UMTS/WCDMA performance requirements.
  • Meets HSDPA performance requirements.
  • Single positive-supply operation with low power and shutdown modes.
  • 3.4V typical Vcc operation.
  • Low Vref (2.85V) compatible with advanced handset chipsets.
  • C.
