The Qorvo® QPB9325 is a highly integrated front-end module targeted for TDD macro or picocell base stations. The LNA switch module integrates RF functional blocks such as a pin-diode based high power switch capable of handling up to 52 W with an LTE signal (8 dB PAR) along with two LNA stages. Further integration is also implemented where the pin diode driver and dc-dc converter circuits are implemented inside the module to enable only the need for an external 5 V power supply. The control voltage for the switch and gain control mode is with 3.3 V logic.
The QPB9325 can be utilized across the 3.6 - 3.8 GHz range to provide 1.2 dB noise figure 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 switch allows for power levels up to 360 W peak power to be routed to an external load termination.
The QPB9325 is packaged in a RoHS-compliant, compact 8 x 8 mm surface-mount leadless package. The switch LNA module is targeted for wireless infrastructure applications configured for TDD-based architectures.
Typical Applications
- Wireless Infrastructure
- Macro or Picocell base stations
- TDD-based Architectures
