The QPB9319 from Qorvo is a highly integrated front end module developed for TDD base stations. It consists of a high power SPDT switch and a two-stage Low Noise Amplifier that operate from 1.8 to 4.2 GHz. The second stage LNA is capable of going into bypass mode. The switch is based on SOI technology and can handle input RF power signals of up to 5W average power assuming an 8 dB PAR. The FEM requires a single 5V supply to operate both the switch and LNA.
The QPB9319 is available in a RoHS-compliant, compact 7 x 7 mm surface-mount leadless package. The switch LNA module is targeted for wireless infrastructure applications configured for TDD-based MIMO architectures. The module can be used for next generation 5G or pre-5G solutions or small cell base-station applications.
