QPB9325 High Power Switch LNA Module Product Overview 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 16 Pin 8mmx8mm Leadless SMT Package control voltage for the switch and Gain control. mode is with 3.3 V logic. Key Features The QPB9325 can be utilized across the 3.3-4.2 GHz range 3.3-4.2 GHz frequency range to provide 1.2 dB noise figure for operation in the receive Integrates a high-power switch, two LNA stages, pin mode and 0.5 dB insertion loss in the transmit mode. The diode driver circuits, and dc converter LNAs utilize Qorvos high performance E-pHEMT process while the switch allows for power levels up to 360 W peak Ideal for TDD systems with an isolator power to be routed to an external load termination. Only requires a 5 V supply with 3.3 V logic Ctrl. Max RF Input power: 52 W Pavg (8 dB PAR) The QPB9325 is packaged in a RoHS-compliant, compact 34.1 dB gain 8x8 mm surface-mount leadless package. The switch LNA 1.2 dB noise figure module is targeted for wireless infrastructure applications configured for TDD-based architectures. -2.2 dBm IIP3 (Rx mode) 0.5 dB Insertion Loss (Tx mode) Compact package size, 8x8 mm Functional Block Diagram Pin 1 Reference Mark Applications Package Topside 1 12 ANT RXOUT Wireless Infrastructure LNA Macro or picocell base stations 2 11 NC NC TDD-based architectures 10 T/R 3 CB LNA DC-DC Conversion 4 9 CA Vcc Ordering Information Exposed Backside Pad Part No. Description GND QPB9325TR13 2500 pcs on a 13 reel QPB9325EVB Evaluation board Top View Datasheet, October 15, 2021 Subject to change without notice 1 of 16 www.qorvo.com 5 16 LA TERM 6 15 LB NC 7 14 NC DA 8 13 NC DB QPB9325 High Power Switch LNA Module Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Storage Temperature -50 to +150C VCC +4.75 +5 +5.25 V T/R Mode Low Voltage 0 0.8 V Max Operating Temperature +115C V +6 V T/R Mode High Voltage 2.0 3.6 V CC (1) T 40 +105 C RF at ANT (Tx Mode) +47.2 dBm CASE 6 (3) (2) Tj for >10 hours MTTF +190 C RF at ANT (Tx Mode) +44.2 dBm Notes: (2) RF at ANT (Rx Mode) +20 dBm 3.
