General Description
The RMPA2271 Power Amplifier Module (PAM) is Fairchild’s latest innovation in 50Ω matched, surface mount modules targeting WCDMA/UMTS applications. Answering the call for integrated Power Detection, the RMPA2271 offers the ability to measure power output over a 20dB range. This feature eliminates the need of an external power detector and lossy directional coupler, improving system perfomance and reducing overall cost.

Features
■ Temperature compensated, integrated power detector with >20dB dynamic range
■ 41% WCDMA efficiency at +28dBm average output power 1920–1980MHz
■ Meets UMTS/WCDMA and HSDPA performance requirements
■ Compact Lead-free compliant LCC package– (3.0 x 3.0 x 1.0 mm nominal)
■ Single positive-supply operation and low power and shutdown modes
■ Low Vref (2.85V) compatible with advanced handset chipsets
