Antennas RF Procurement Notes

Verify the specific flange type matches the installation requirements before purchase. Confirm that the operating frequency aligns with the 8.2 GHz to 12.4 GHz range. Check for any environmental sealing needs if used in non-standard conditions. Ensure the receiving equipment supports the WR-90 waveguide dimensions. Review manufacturer documentation for handling instructions regarding precision surfaces.

Antennas RF Selection Notes

Select this model when a fixed-gain solution is required for the X-band spectrum. Compare against lower gain variants if broader beamwidth is necessary. Consider the physical size constraints imposed by the horn structure. Evaluate the UG-135/U interface against available waveguide ports. Assess whether the 20 dBi gain meets the system link budget requirements without excessive amplification.

Antennas RF Part Context

This component belongs to the family of WR-90 waveguide antennas designed for the X-band. It serves as a passive RF transducer converting guided waves to free-space radiation. The product line includes various gain options and flange types. This specific model emphasizes high gain for directional applications. It complements other waveguide accessories like shims and dividers from the same manufacturer.

Antennas RF Replacement Considerations

Substitute only with models explicitly listed as compatible equivalents by the manufacturer. Verify identical WR-90 waveguide dimensions to ensure mechanical fit. Confirm matching frequency range and gain specifications to maintain system performance. Check for equivalent flange standards such as UG-135/U. Do not use generic horn antennas without verifying precise electrical parameters.
