QPQ1903SR

Overview

The QPQ1903SR is a Bulk Acoustic Wave (BAW) band-pass filter manufactured by Qorvo. It operates with a center frequency of 5.25 GHz and provides a bandwidth of 160 MHz. The component exhibits an insertion loss of 1.5 dB. It is housed in a compact 3-SMD, no-lead package designed for board mounting applications.

Feature Summary

• Utilizes Bulk Acoustic Wave technology for high-performance signal conditioning
• Features extremely steep skirt characteristics for precise frequency selection
• Designed specifically for 5GHz Wi-Fi UNII1-2A band applications

Applications

• 5GHz Wi-Fi UNII1-2A band filtering
• Wireless local area network (WLAN) systems
• Signal conditioning in RF front-end modules

Procurement Notes

Verify the specific suffix SR against official Qorvo documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with surface-mount assembly processes given the no-lead SMD form factor. Cross-reference the center frequency and bandwidth requirements with system design constraints before procurement.

Selection Notes

Select this component when designing for the 5.25 GHz center frequency with a 160 MHz bandwidth requirement. The low 1.5 dB insertion loss makes it suitable for sensitive RF paths. Consider the 3-SMD package size for space-constrained PCB layouts requiring BAW filter performance.

Part Context

This part belongs to Qorvo's signal conditioning portfolio, specifically within the bandpass filter category. It is categorized under wireless and RF integrated circuits, targeting modern wireless communication standards that require high selectivity and low loss in the 5 GHz spectrum.

Replacement Considerations
