WSBP-26G+

Overview

The WSBP-26G+ is a Substrate Integrated Waveguide (SIW) bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 25 GHz to 27 GHz, providing a center frequency of 26 GHz and a bandwidth of 2 GHz. The component features a 3 dB passband insertion loss and maintains a 50 Ohm impedance. It utilizes a shielded construction for high rejection performance and is available in a 3-SMD, No Lead surface-mount package. The device supports a minimum operating temperature of -40 C.

Feature Summary

• Utilizes Substrate Integrated Waveguide (SIW) technology for effective signal filtering
• Features shielded construction to ensure high rejection characteristics
• Designed for low insertion loss within the specified microwave frequency range

Applications

• Microwave communication systems requiring precise bandpass filtering
• Radio frequency front-end modules operating in the 25-27 GHz range
• Test and measurement equipment utilizing SIW filter components

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update performance curves or mechanical drawings without changing the base part number. Confirm that the 3-SMD No Lead termination style matches your PCB footprint requirements. Ensure your design accounts for the -40 C minimum operating temperature limit. Cross-reference the impedance specification with your system's transmission line characteristics to maintain signal integrity.

Selection Notes

Select this component when a compact, high-rejection filter is needed for the 25-27 GHz spectrum. The SIW construction offers a balance between performance and size compared to traditional waveguide solutions. Consider the SMT package for automated assembly processes. Evaluate the insertion loss specifications against your link budget requirements. This model is suitable for applications demanding stable performance in microwave frequencies.

Part Context

This component belongs to Mini-Circuits' WSBP series of Substrate Integrated Waveguide filters. These components are designed to provide robust filtering solutions for microwave applications. The series typically includes various center frequencies and bandwidths to suit different RF system needs. The WSBP-26G+ specifically targets the 26 GHz region, offering a standardized solution for engineers designing systems in this frequency band.

Replacement Considerations

Check Mini-Circuits documentation for other WSBP models with similar center frequencies if exact specifications do not match. Verify that any substitute maintains the 50 Ohm impedance and compatible SMD package dimensions. Ensure the replacement filter meets the required bandwidth and rejection criteria for your specific application.
