B39162B8389P810

Overview

The B39162B8389P810 is a Surface Acoustic Wave (SAW) filter manufactured by Qualcomm for Global Navigation Satellite System (GNSS) applications. It operates at a center frequency of 1.583 GHz with a bandwidth of 48 MHz and insertion loss of 1.8 dB. The component utilizes a double-hump filter design to enhance signal selectivity. It is housed in a compact 5-SMD, no-lead surface mount package measuring 1.10 mm x 0.90 mm with a maximum height of 0.45 mm. The device meets AEC-Q200 automotive qualification standards and complies with RoHS3 regulations.

Feature Summary

• Double-hump SAW filter architecture designed for enhanced GNSS signal rejection
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 5-SMD surface-mount footprint suitable for space-constrained designs

Applications

• GPS receiver front-end filtering
• GNSS module signal conditioning
• Automotive navigation systems

Procurement Notes

Verify the specific datasheet revision and manufacturing origin before integration. Confirm that the 5-SMD package dimensions align with the target PCB land pattern. Ensure compliance with local environmental directives such as RoHS3 and REACH requirements for the intended market.

Selection Notes

Select this component when dual-band or wideband GNSS reception requires specific out-of-band rejection characteristics provided by the double-hump topology. Compare insertion loss and bandwidth specifications against alternative single-hump filters to ensure compatibility with the system's noise figure budget and channel spacing requirements.

Part Context

This part belongs to the Qualcomm RF front-end filter portfolio, specifically engineered for satellite navigation receivers. It addresses the need for high-selectivity filtering in modern multi-constellation GNSS modules where interference from adjacent bands must be minimized while maintaining low signal attenuation.
