QPB9328 Dual-Channel Switch LNA Module Product Overview The QPB9328 is a highly integrated front-end module targeted for TDD base stations. The LNA switch module integrates a two-stage LNA and a high-power switch in a dual channel configuration. Power down capability for the LNAs can be controlled with shut-down pins for the module. The QPB9328 can be utilized across the 4.45.0GHz 32 Pad 6mmx6mm leadless SMT Package range to provide 1.8 dB noise figure for operation in the receive mode and 0.65dB insertion loss in the transmit mode. The LNAs utilize Qorvos high performance E- Key Features pHEMT process while the pin-diode based switch supports input RF power signals of up to 10W average power 4.4-5.0 GHz Frequency Range assuming 8dB PAR. Integrates dual channels of a two-stage LNA with high power switches The QPB9328 is packaged in a RoHS-compliant, compact 6mm x 6mm surface-mount leadless package. The switch Max RF Input power: 10W Pavg (8 dB PAR) LNA module is targeted for wireless infrastructure 1.8 dB Noise Figure (Rx mode) applications configured for TDD-based MIMO 32 dB Gain (Rx mode) architectures. The module can be used for next generation +34 dBm OIP3 (Rx mode) 5G or pre-5G solutions or small cell base station 0.65 dB Insertion Loss (Tx mode) applications.
