Qorvo QPB9351 1.7GHz to 2.7GHz Dual Channel Rx VGAs
Qorvo QPB9351 1.7GHz to 2.7GHz Dual Channel Rx VGAs are developed for high-performance macro base station receivers. The highly integrated Rx front-end module combines high-performance first-stage low noise amplifiers (LNA), digital step attenuators (DSA), and a second-stage LNA in a dual-channel configuration. The RX VGA SiP (receive variable gain amplifier system in package) offers power-down capability for the amplifiers, which can be controlled via dedicated shutdown pins for each channel. The LNAs utilize Qorvo’s high-performance E-pHEMT process to supply a 0.4dB noise figure for the first stage LNA. Gain control is implemented through a 31dB range DSA in 1dB steps.
The QPB9351 is available in a RoHS-compliant, compact 5mm x 5mm 32-pin surface-mount leadless package.
