QPQ1028SR

Overview

The QPQ1028SR is a dual-use GPS L1/L2 dual filter manufactured by Qorvo. It operates at frequencies of 1.229 GHz and 1.576 GHz. The component features a bandwidth of 24 MHz and an insertion loss of 3.5 dB. It utilizes Surface Acoustic Wave (SAW) technology and is housed in a 3-SMD, No Lead package. This signal conditioning device is designed for board mount installation via SMD/SMT termination.

Feature Summary

• Supports dual-frequency GPS reception covering both L1 and L2 bands
• Utilizes Surface Acoustic Wave (SAW) technology for signal filtering
• Designed for compact board mount integration using surface-mount packaging

Applications

• GPS L1/L2 dual-band receiver front-ends
• GNSS signal conditioning modules
• Navigation system RF filtering stages

Procurement Notes

Verify the current lifecycle status as the product is listed as End-of-Life with discontinuation notifications. Confirm availability through authorized distributors as stock levels may be limited or depleted. Ensure compatibility with existing PCB footprints before procurement due to potential supply chain constraints associated with obsolete components.

Selection Notes

Select this component specifically for applications requiring simultaneous L1 and L2 band filtering. Verify that the 24 MHz bandwidth meets the system's spectral requirements. Consider the 3.5 dB insertion loss impact on overall receiver sensitivity. Evaluate alternative active solutions if passive SAW performance limits are insufficient for the specific link budget.

Part Context

This part belongs to Qorvo's signal conditioning portfolio, specifically within the filters sub-category. It is categorized under wireless and radio frequency integrated circuits.
