FMW28F011

Overview

The FMW28F011 is a WR-28 bandpass waveguide filter manufactured by Fairview Microwave. It operates within a frequency range of 35 GHz to 37 GHz. The component features an insertion loss of 0.5 dB and provides a rejection level of 40 dB. It supports an input power capacity of 50 W. The unit is constructed for high-power RF applications in the K-band spectrum.

Feature Summary

• Provides selective signal transmission within the specified 35 GHz to 37 GHz passband
• Maintains low signal attenuation with 0.5 dB insertion loss characteristics
• Offers strong out-of-band interference suppression achieving 40 dB rejection
• Engineered to handle high power levels up to 50 W input capacity

Applications

• High-frequency communication systems requiring precise band selection
• Radar systems operating in the K-band spectrum
• Test and measurement equipment needing stable signal filtering
• Satellite ground station receiver front-ends

Procurement Notes

Verify the specific WR-28 flange configuration and coupling method required for your system integration before ordering. Confirm that the 50 W power rating aligns with your peak signal expectations. Ensure the 35 GHz to 37 GHz bandwidth matches your operational frequency requirements precisely. Check for any specific mounting hardware needs associated with the waveguide interface.

Selection Notes

Select this component when a narrow bandpass response is critical between 35 GHz and 37 GHz. The 0.5 dB insertion loss makes it suitable for sensitive receiver chains where signal integrity is paramount. The 40 dB rejection capability ensures effective noise reduction from adjacent channels. Consider the 50 W power handling if the application involves high-energy transmit signals or robust test environments.

Part Context

This part belongs to Fairview Microwave's WR-28 waveguide filter series, designed for millimeter-wave applications. It complements other RF interconnects and signal conditioning components in the same frequency range. The product addresses the need for reliable filtering in high-performance microwave systems where standard coaxial solutions are insufficient due to size or power constraints.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other WR-28 bandpass filters from Fairview Microwave or competitors with matching 35-37 GHz specifications. Verify mechanical dimensions and flange types to ensure compatibility with existing waveguide assemblies.
