FMWAN090-20SM

Antennas RF Overview

The FMWAN090-20SM is a general purpose horn antenna manufactured by Fairview Microwave. It operates within the X-band frequency range of 8.2 GHz to 12.4 GHz, corresponding to the WR-90 waveguide standard. The component features an SMA male connector interface and utilizes a UG-135/U type flange for mounting. Designed for standard gain applications, this antenna provides a nominal gain of 20 dBi. The construction supports reliable RF transmission in microwave systems requiring precise directional radiation patterns.

Antennas RF Procurement Notes

Verify the specific datasheet version for the FMWAN090-20SM to confirm mechanical dimensions and flange tolerances. Ensure compatibility with existing UG-135/U mating hardware. Check for any recent manufacturing updates that may affect connector plating or material specifications. Confirm operational temperature ranges align with system requirements before finalizing procurement orders.

Antennas RF Selection Notes

Select this model when a 20 dBi gain level is required for X-band applications. The SMA male interface dictates cable selection and adapter needs. Consider the physical size constraints imposed by the WR-90 horn structure. Evaluate environmental sealing requirements if outdoor deployment is planned, as standard models may lack specialized weatherproofing.

Antennas RF Part Context

This antenna belongs to the Fairview Microwave WR-90 series, designed for the 8.2–12.4 GHz band. Related variants include lower gain models like the FMWAN090-10 and higher gain options such as the FMWAN090-15ELSF. These components share common waveguide standards but differ in directivity and connector configurations to suit diverse system architectures.

Antennas RF Replacement Considerations

Direct substitutes include other manufacturers' WR-90 horn antennas with identical 20 dBi gain and SMA male interfaces. Verify flange dimensions match UG-135/U standards. Cross-reference impedance characteristics to ensure 50-ohm continuity. Alternative models may require different mounting brackets due to varying horn lengths.
