Integrated Switch LNA Targets TDD MIMO

Qorvo’s QPB9319 Integrated Switch LNA Targets TDD MIMO across the 1.8 – 4.2 GHz frequency rangeRFMW, Ltd. announces design and sales support for a highly integrated Front-End module. Qorvo’s QPB9319 integrates a two-stage LNA and a high power switch in a dual channel configuration. Supporting applications across the 1.8 – 4.2 GHz frequency range, this FEM provides 1.45 dB noise figure for operation in the receive mode and 0.7 dB insertion loss in the transmit mode. The switch handles input RF power up to 8W average, while needing only a +5V supply for both switch and LNA operation. The QPB9319 switch LNA module is targeted for wireless infrastructure applications configured for TDD-based MIMO architectures and can be used for next generation 5G, pre-5G or small cell base-station applications. Packaged in a RoHS-compliant, compact 7 mm x 7 mm surface-mount leadless package.
