Overview
The HV-AT(1)-PJ is a 1.85mm coaxial attenuator manufactured by Hirose Electric Co Ltd. It provides a fixed attenuation of 1dB with a characteristic impedance of 50 Ohms. The component supports a frequency range extending up to 67GHz and complies with IEC 61169-32 standards for 1.85mm connectors. It is RoHS2 compliant, ensuring environmental safety in manufacturing.
Feature Summary
- Provides precise 1dB signal attenuation for high-frequency applications
- Supports operation within a wide frequency range up to 67GHz
- Features 50 Ohm impedance matching for standard RF systems
- Complies with IEC 61169-32 standards for 1.85mm coaxial interfaces
Applications
- High-frequency test and measurement equipment calibration
- RF signal path power level adjustment
- Component characterization in microwave laboratories
- Signal integrity verification in high-speed digital systems
Procurement Notes
Verify the specific model suffix PJ against official Hirose documentation to ensure correct interface compatibility. Confirm RoHS2 compliance status through current datasheets. Check for discontinued status or lifecycle changes via manufacturer PCN notices before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1dB attenuation is required at 50 Ohms. Ensure the operating environment does not exceed the 67GHz upper frequency limit. Verify mechanical fitment for 1.85mm connector systems. Consider thermal management requirements if used in high-power continuous wave applications.
Part Context
This part belongs to the HV-AT series of coaxial attenuators from Hirose Electric. It complements other values in the series such as HV-AT(2)-PJ and HV-AT(4)-PJ. The series targets precision RF applications requiring stable attenuation characteristics across broad bandwidths.
Replacement Considerations
HV-AT(2)-PJ offers 2dB attenuation. HV-AT(4)-PJ provides 4dB attenuation. Both share the same 1.85mm form factor and 50 Ohm impedance. Verify exact dB value requirements before substituting.
