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.
