FMWAN137-20

Antennas RF Overview

The FMWAN137-20 is a WR-137 standard gain horn antenna manufactured by Fairview Microwave. It operates within the 5.85 GHz to 8.2 GHz frequency range and provides a nominal gain of 20 dBi. The device features specific beamwidth characteristics, with an E-plane width of 17.3 degrees and an H-plane width of 17.5 degrees. This component is designed for high-performance microwave applications requiring directional signal transmission or reception.

Antennas RF Feature Summary

• Standard gain horn design optimized for WR-137 waveguide dimensions
• Provides consistent 20 dBi gain across the designated frequency band
• Engineered with precise E-plane and H-plane beamwidth specifications

Antennas RF Applications

• Microwave point-to-point communication links
• Radar system test and measurement setups
• Satellite ground station uplink/downlink antennas

Antennas RF Procurement Notes

Verify the specific connector interface required for your installation, as this model designation typically corresponds to variants such as SMA Female (FMWAN137-20SF) or N Female (FMWAN137-20NF). Confirm that the operating frequency aligns with the 5.85 GHz to 8.2 GHz specification before procurement to ensure compatibility with existing RF infrastructure.

Antennas RF Selection Notes

Select this component when a WR-137 form factor is mandatory for your waveguide system. Ensure the required gain meets the 20 dBi specification and that the operational bandwidth covers the 5.85 GHz to 8.2 GHz range. Consider the specific connector type needed for mating with your source equipment.

Antennas RF Part Context

This part belongs to the Fairview Microwave FMWAN series of standard gain horn antennas. These components are engineered to interface directly with rectangular waveguides, providing reliable performance in microwave frequencies. The WR-137 size indicates operation in the lower millimeter-wave spectrum.

Antennas RF Replacement Considerations

Direct substitutes include FMWAN137-20SF and FMWAN137-20NF. Verify that any replacement maintains the WR-137 waveguide interface and matches the 20 dBi gain requirement.
