B39162B4393P810 GNSS SAW Diplexer Specifications and Applications

ElecSuppliers Part Number GuideSep 26, 2026

B39162B4393P810 is a GNSS SAW diplexer designed for multi-band satellite positioning applications. The device is associated with Qualcomm RF Front-End filter products and is designed to combine and separate GNSS frequency bands within a compact RF front-end architecture.

The part is listed as a CSSP device with a compact 1.5 mm × 1.1 mm package size. Its small footprint makes it suitable for GNSS receiver designs where RF performance and PCB space are both important.

B39162B4393P810 Frequency Bands

B39162B4393P810 supports multiple GNSS frequency bands through its diplexer architecture. Published RF filter information identifies one path covering L5, B2a, E5, G3 and L2-G2 bands and another path covering L1, E1, G1 and B1 bands.

The listed frequency ranges are approximately 1166 MHz to 1251 MHz for the lower-frequency path and 1550 MHz to 1607 MHz for the higher-frequency path.

This multi-band configuration allows a GNSS receiver to handle signals from different satellite navigation systems while maintaining a compact RF signal path.

B39162B4393P810 RF Performance

B39162B4393P810 is designed for post-LNA use and is optimized for high selectivity and low group delay. Published specifications list typical insertion-loss ranges of approximately 1.3 dB to 1.6 dB for the first path and 1.5 dB to 1.6 dB for the second path.

High selectivity is important in GNSS receivers because unwanted signals and adjacent-band interference can reduce receiver sensitivity and positioning performance. A dedicated SAW diplexer provides frequency separation before subsequent RF processing stages.

B39162B4393P810 Package

The B39162B4393P810 uses a compact CSSP package with an approximate footprint of 1.5 mm × 1.1 mm. The small package is well suited to mobile and embedded GNSS equipment where antenna matching, RF filtering, amplification, and baseband circuitry must fit within limited PCB space.

Because GNSS RF layouts are sensitive to parasitic effects, the recommended PCB land pattern and RF routing practices should be followed during design. Short signal paths and appropriate grounding can help maintain the expected filter performance.

B39162B4393P810 GNSS Applications

B39162B4393P810 can be used in multi-constellation GNSS receiver designs that require compact filtering for several satellite navigation bands. Potential applications include automotive navigation systems, telematics devices, asset tracking equipment, industrial positioning systems, precision navigation equipment, and connected devices with integrated GNSS.

The device can also be considered for applications that combine signals from GPS, Galileo, BeiDou, GLONASS, and other supported satellite navigation systems.

B39162B4393P810 RF Front-End Design

A GNSS receiver typically includes an antenna, matching network, filtering, low-noise amplification, additional RF filtering, and a GNSS receiver IC. The diplexer is used to separate or combine frequency paths while limiting unwanted signals entering the receiver chain.

B39162B4393P810 is positioned for post-LNA filtering. This makes its selectivity and group-delay characteristics important when designing the complete RF front end.

Engineers should evaluate the filter together with the antenna, LNA, receiver IC, PCB transmission lines, and other RF components. Substituting another GNSS filter solely on the basis of package size may result in different insertion loss, bandwidth, rejection, or group-delay performance.

B39162B4393P810 Selection Considerations

When selecting B39162B4393P810, engineers should verify the supported GNSS frequency bands, insertion loss, rejection requirements, package dimensions, RF impedance, signal routing, and operating conditions.

The complete manufacturer part number should also be checked before procurement because similar Qualcomm RF360 part numbers can have different frequency combinations and filter configurations.

For new designs, the electrical characteristics of the exact production version should be compared with the RF requirements of the receiver. Particular attention should be given to insertion loss and selectivity because these parameters directly affect the RF signal budget.

B39162B4393P810 Sourcing

B39162B4393P810 is a specialized GNSS RF filter with a specific frequency configuration, so buyers should source the exact part number rather than using a generic GNSS SAW filter as a substitute.

For procurement, buyers should provide the complete part number, required quantity, target delivery schedule, and packaging requirements. For high-volume projects, availability and lead time should be confirmed before finalizing the purchasing plan because specialized RF filters may have longer supply cycles than common passive components.

When considering an alternative, engineers should verify frequency coverage, insertion loss, package size, pin configuration, and RF performance before approving the replacement.

B39162B4393P810 for Multi-Band GNSS

B39162B4393P810 provides a compact filtering solution for multi-band GNSS receivers. Its CSSP package, dual-path frequency coverage, high selectivity, and low group-delay characteristics make it suitable for compact RF front-end designs where several satellite navigation bands need to be processed through a limited PCB area.

For production applications, the final component selection should be based on the complete GNSS RF architecture and the required performance of the finished equipment.
