Procurement Notes

Verify the specific part number HV-AT(5)-PJ against official Hirose Electric documentation to confirm the 5 dB attenuation value and 1.85mm interface compatibility. Ensure that the required tolerance (+0.7/-0.4 dB) meets your system specifications. Confirm that the 1W power rating and 67 GHz frequency limit are suitable for your operational environment before procurement.

Selection Notes

Select this component when a fixed 5 dB attenuation is required in a 50 Ohm system using 1.85mm connectors. Consider the 67 GHz upper frequency limit and 1W power handling capacity. Compare against other values in the HV-AT series if different attenuation levels are needed, ensuring the physical form factor matches your existing infrastructure.

Part Context

This component belongs to the HV-AT series of RF attenuators designed for 1.85mm coaxial systems. It is part of Hirose's portfolio of precision RF components intended for high-frequency applications. The series includes various attenuation values, with this specific model providing 5 dB of loss while maintaining standard 50 Ohm impedance characteristics.

Replacement Considerations

Check for other models in the HV-AT series with different attenuation values if the 5 dB specification does not match requirements. Verify that any substitute maintains the 1.85mm interface and 50 Ohm impedance. Consult official Hirose Electric cross-reference data for confirmed compatible alternatives.
