®
High Power Switch LNA Module
Product Overview
The Qorvo® QPB9324 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 QPB9324 can be utilized across the 3.4-3.6 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 330 W peak
power to be routed to an external load termination.
The QPB9324 is packaged in a RoHS-compliant, compact
8x8 mm surface-mount leadless package. The switch LNA
module is targeted for wireless infrastructure applications
configured for TDD-based architectures.

Pin is a CW signal swept from 3.4 to 3.6GHz. Specification refers to any mixing product that occurs in 3.4 to 3.6GHz band.
Follow Qorvo EVB layout for lowest spur level, any deviation may increase spur level.
Measure Pout with IBW = 4.5MHz over frequency range with no input power applied.
