Product Description

The QPB9350 is a highly integrated Rx front-end module

targeted for high performance macro base station

receivers. The RX VGA SiP (receive variable gain amplifier

system in package) integrates high performance first stage

low noise amplifiers (LNA), digital step attenuators (DSA),

second stage LNA in a dual channel configuration. Power

down capability for the amplifiers can be controlled through

dedicated shutdown pins for each channel.

The LNAs utilize Qorvo’s high performance E-pHEMT

process to provide 0.4 dB noise figure for the first stage

LNA. Gain control is implemented through a 31 dB range

DSA in 1 dB steps.

The QPB9350 is packaged in a RoHS-compliant, compact

5 x 5 mm 32 pin surface-mount leadless package.
