QPB9350
0.4 - 1.0 GHz Dual Channel Rx Digital Variable Gain Amplifier
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.
