B280MD1S-T

Overview

The B280MD1S-T is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It operates at a center frequency of 28 GHz with a bandwidth of 3 GHz and an insertion loss of 3 dB. The component features a 50 Ohm impedance and utilizes a 10-SMD, no lead package configuration. It supports board mounting and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides precise bandpass filtering at 28 GHz with a 3 GHz bandwidth
• Utilizes low-loss, temperature-stable materials for minimal performance variation
• Designed for compact surface mount integration in RF systems

Applications

• High-frequency RF signal conditioning
• Microwave communication systems
• Test and measurement equipment requiring stable bandpass filtering

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm that the 10-SMD no-lead package dimensions match your PCB footprint requirements. Ensure compatibility with 28 GHz operational environments and validate thermal stability specifications against your system's operating temperature range before finalizing procurement.

Selection Notes

Select this component for applications requiring a fixed 28 GHz center frequency with a 3 GHz bandwidth. The 3 dB insertion loss specification should be evaluated against system link budget requirements. Consider the 10-SMD package size for space-constrained designs and verify that the 50 Ohm impedance aligns with your transmission line characteristics.

Part Context

This part belongs to the B-series bandpass filters from Knowles Dielectric Labs, which are engineered for high-frequency RF applications. The series typically employs proprietary low-loss dielectric materials to maintain performance stability across varying temperatures. These filters are distinct from gain equalizers or general-purpose capacitors in the manufacturer's portfolio.

Replacement Considerations

The DEB-B280MD1S is an evaluation board for this component, not a substitute. No direct public substitute part numbers are confirmed for replacement purposes.
