The QPB9378 is a highly integrated RF front-end module targeted for 5G TDD base stations. The module integrates a two-stage LNA and a high-power SPDT switch in a dual channel configuration. It features a 2nd stage LNA with bypass functionality and power down mode for LNA when in transmit mode.
The QPB9378 can be operated across the 2.3 – 5.0 GHz range. It provides 1.25 dB noise figure and 33.5dB gain at 3.6 GHz for operation in the receive mode and 0.5 dB insertion loss in the transmit mode. The switch supports input RF power signals of up to 20 W average power assuming 9 dB PAR.
The QPB9378 is packaged in a RoHS-compliant, compact 6 x 6 mm surface-mount leadless package. The switch LNA module is targeted for wireless infrastructure applications configured for 5G TDD-based MIMO architectures.
Typical Applications
- 5G m-MIMO
