HV-AT(2)-PJ

Overview

The HV-AT(2)-PJ is a fixed RF attenuator manufactured by Hirose Electric Co Ltd. It provides an attenuation value of 2 dB with a characteristic impedance of 50 ohms. The component utilizes the 1.85mm coaxial connector interface, compliant with IEC standards. It supports a frequency range extending up to 67 GHz. The device is designed for high-frequency signal processing applications requiring precise power reduction.

Feature Summary

• Provides fixed 2 dB attenuation at 50 ohms impedance
• Utilizes 1.85mm coaxial interface compliant with IEC standards
• Supports operation up to 67 GHz frequency range

Applications

• High-frequency test and measurement equipment
• RF signal generation and distribution systems
• Microwave circuit calibration setups

Procurement Notes

Verify part status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm compatibility with existing 1.85mm connector infrastructure. Ensure environmental specifications meet application requirements. Cross-reference datasheet CL0354-0289-0-00 for accurate technical parameters. Validate substitute availability if original supply is unavailable.

Selection Notes

Select this component when a fixed 2 dB attenuation is required in 50 ohm systems operating within the 1.85mm connector standard. Consider the 67 GHz upper frequency limit for suitability in microwave applications. Evaluate mechanical dimensions and mounting requirements against system constraints. Compare against other HV-AT series variants for different attenuation values if necessary.

Part Context

The HV-AT(2)-PJ belongs to the HV-AT series of RF attenuators from Hirose Electric. This series includes various attenuation values such as 3 dB, 4 dB, and 7 dB options sharing the same 1.85mm interface. These components are engineered for precision in high-frequency environments, supporting reliable signal integrity across wide bandwidths in professional electronic testing scenarios.

Replacement Considerations

Public confirmed substitutes include HV-AT(3)-PJ, HV-AT(4)-PJ, and HV-AT(7)-PJ from the same manufacturer series. These alternatives offer different attenuation values while maintaining identical 1.85mm interface and 50 ohm impedance characteristics. Verify specific attenuation requirements before selecting alternative models.
