QPA9501 3-Stage LTE-U/LAA Power Amplifier General Description The QPA9501 is high power amplifier module containing an internally matched 3-stage PA, compensated DC biasing circuit and output power detector. This PA module is optimized for the WiFi bands from 5.1-5.9GHz and hence well suited for LTE-U/LAA applications. It provides high gain (32dB) and -47dBc ACLR at Pout of 22dBm with a 20MHz LTE signal without any DPD. 4x4mm 20-pin Leadless QFN Package The QPA9501 features chipset logic compatible control Product Features voltages and buffered PA enable pin (PAEN) all of which draw very low current to facilitate ease of use and 4.9 GHz to 5.9 GHz Operational Bandwidth compatibility with current and future transceiver Fully Integrated Power Amplifier Module With Power generations. With its optimized power dissipation, this Detector amplifier module is well suited for implementation into next generation MIMO configurations and well designed to work Internally Matched Input/Output with or without digital pre-distortion (DPD). -47dBc ACLR with Pout = 22dBm avg Temperature Compensated Bias Network The QPA9501 is assembled in a small footprint 4.0 x 4.0 x High Gain=32dB 0.85 mm 20-pin QFN package.
