The QPB9348 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 on the module.
The QPB9348 can be operated across the 1.7 - 4.2 GHz range. It provides 1.2 dB noise figure at 3.5GHz for operation in the receive mode and 0.5 dB insertion loss in the transmit mode. The LNAs utilize Qorvo's high performance E-pHEMT process while the pin-diode based switch supports input RF power signals of up to 10W average power assuming 9 dB PAR.
The QPB9348 is packaged in a RoHS-compliant, compact 6 x 6 mm surface-mount leadless package. The switch LNA module is targeted for wireless infrastructure applications
configured for TDD-based MIMO architectures.
Typical Applications
- 5G mMIMO
- Wireless Infrastructure
- Small cell BTS
- TDD-based architectures
