B393KD0S

Overview

The B393KD0S is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It operates with a center frequency of 39.3 GHz and provides a bandwidth of 1.4 GHz. The component features an insertion loss of 2.5 dB and is housed in a 12-SMD, no-lead package suitable for automated assembly.

Feature Summary

• Surface mount construction for direct board integration
• Bandpass filtering capability centered at 39.3 GHz
• Designed for high-frequency signal conditioning

Applications

• RF signal processing circuits
• Wireless communication systems operating near 39.3 GHz
• Signal conditioning modules requiring bandpass characteristics

Procurement Notes

Verify the exact center frequency and bandwidth specifications against the official datasheet before procurement. Confirm that the 12-SMD no-lead package dimensions match the target PCB footprint. Ensure the insertion loss rating meets the system requirements for the intended RF application environment.

Selection Notes

Select this component when a fixed center frequency of 39.3 GHz is required. Consider the 1.4 GHz bandwidth relative to the signal spectrum. Evaluate the 2.5 dB insertion loss impact on overall system gain. Verify compatibility with SMD reflow processes due to the no-lead package type.

Part Context

This part belongs to the bandpass filter category within Knowles Dielectric Labs' signal conditioning portfolio. It utilizes ceramic or similar dielectric materials typical for high-frequency microwave applications. The design focuses on maintaining signal integrity in dense RF environments through precise frequency selection.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching the 39.3 GHz center frequency, 1.4 GHz bandwidth, and 12-SMD package constraints.
