Product Overview

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.
