B380KA1S-T

Overview

The B380KA1S-T is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for radio frequency signal conditioning. It operates at a center frequency of 38 GHz with a bandwidth of 1 GHz and an insertion loss of 4.5 dB. The component utilizes a 3-SMD, no-lead package configuration suitable for automated assembly processes.

Feature Summary

• Provides precise bandpass filtering capabilities in the millimeter-wave spectrum
• Engineered for direct surface mount integration onto printed circuit boards
• Optimized for high-frequency signal integrity within RF systems

Applications

• Millimeter-wave communication infrastructure
• High-frequency radar systems
• Satellite communication equipment

Procurement Notes

Verify the specific datasheet revision to confirm electrical tolerances and pinout definitions before finalizing design integration. Ensure that the 3-SMD no-lead package footprint matches the target PCB layout exactly. Confirm RoHS compliance status if required by regional manufacturing regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability.

Selection Notes

Select this component when a fixed 38 GHz center frequency with 1 GHz bandwidth is required. Consider the 4.5 dB insertion loss impact on system gain budget. Evaluate the thermal management requirements given the small SMD form factor. Compare against alternative filters if tighter bandwidth or lower loss specifications are necessary for the specific application environment.

Part Context

This model belongs to the Knowles Dielectric Labs RF filter portfolio, specifically targeting high-frequency applications. It shares the series designation with other millimeter-wave components like the B160KA1S-T, which operates at 16 GHz. The product line focuses on providing reliable signal conditioning solutions for advanced wireless technologies requiring stable performance at elevated frequencies.

Replacement Considerations

The DEB-B380KA1S is an evaluation board variant rather than a direct functional substitute. No identical public replacement part numbers are confirmed in available documentation. Designers should consult the manufacturer for qualified alternatives if supply constraints arise.
