HV-AT(0)-PJ

Overview

The HV-AT(0)-PJ is a fixed RF attenuator manufactured by Hirose Electric Co Ltd. It provides an attenuation value of 0 dB with a characteristic impedance of 50 ohms. The component utilizes a 1.85mm connector interface and supports a frequency range from DC to 50 GHz. It has a rated power handling capacity of 2 watts. The device is designed for high-frequency signal applications requiring precise impedance matching and signal level control within the specified operational limits.

Feature Summary

• Incorporates a 1.85mm connector interface for high-frequency signal transmission
• Provides a fixed 0 dB attenuation value maintaining system signal integrity
• Features a 50 ohm characteristic impedance for standard RF system compatibility
• Supports operation up to 50 GHz with 2 watts rated power handling

Applications

• High-frequency test and measurement equipment signal conditioning
• Microwave communication systems requiring precise impedance matching
• RF circuit design and development for signal path integration
• Laboratory instrumentation for signal level verification

Procurement Notes

Verify the specific part number HV-AT(0)-PJ against official Hirose Electric documentation to confirm the 0 dB attenuation specification and 1.85mm interface type. Ensure that the 50 GHz frequency range and 2W power rating align with your application requirements before procurement. Cross-reference datasheets to confirm package details and mounting specifications.

Selection Notes

Select this component when a 0 dB attenuation value is required in a 50 ohm system using a 1.85mm interface. Consider the 50 GHz upper frequency limit and 2W power handling capability relative to your signal environment. Evaluate mechanical fit and thermal management needs for the intended installation location within the RF assembly.

Part Context

This component belongs to the Hirose Electric AT series of terminators and attenuators, which includes various fixed attenuation values such as 3 dB and 6 dB variants like the HV-AT(3)-PJ and HV-AT(6)-PJ. These devices are designed for high-frequency applications requiring reliable signal processing and impedance control in microwave and millimeter-wave systems.

Replacement Considerations

Compatible substitutes include other 0 dB attenuators with 1.85mm interfaces and 50 ohm impedance from Hirose or other manufacturers. Verify that alternative parts match the 50 GHz frequency range and 2W power rating. Ensure mechanical dimensions and connector gender compatibility for direct replacement in existing assemblies.
