Product Overview

The QPB9319 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 is

capable of going into a bypass mode. Power down and

bypass capability for the LNAs can be controlled with

control pins on the module.

The QPB9319 can be utilized across the

1.8 – 4.2 GHz

range to provide 1.45

 dB noise figure for operation in the

receive mode and 0.7

 dB insertion loss in the transmit mode

at 2.7GHz

. The LNAs utilize Qorvo’s high performance E-

pHEMT process while the SOI technology based switch

supports input RF power signals of up to 5W average power

assuming 8

 dB PAR. The product only needs a +5V supply

to operate the high power switch and the LNAs.

The QPB9319 is packaged in a RoHS-compliant, compact

7 mm x 7 mm surface-mount leadless package. The switch
