The QPB9329 is a highly integrated front-end module targeted for TDD base stations. The switch LNA module integrates a two-stage LNA and a high power switch in a dual channel configuration. The second stage LNA has a bypass mode. Power down and bypass capability for the LNAs can be controlled with control pins on the module.
The QPB9329 can be utilized across the 3.8 – 6.0 GHz range to provide 1.8 dB noise figure for operation in the receive mode and 1.1 dB insertion loss in the transmit mode at 4.5 GHz. The LNAs utilize Qorvo’s high performance EpHEMT process while the SOI technology based switch supports input RF power signals of up to 8W average power assuming 8 dB PAR. The product only needs a +5V supply to operate the high-power switch and the LNAs.
The QPB9329 is packaged in a RoHS-compliant, compact 7 mm 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.
