H2.4-AT(1)-PJ

Attenuators Overview

The H2.4-AT(1)-PJ is a 50 Ohm attenuator terminator from the Hirose H2.4 series, designed for millimeter-wave applications up to 40 GHz. It features a female SMA mating interface and a threaded mounting style. The component utilizes gold plating on brass housings and beryllium copper contacts with PTFE insulation. Key electrical specifications include a maximum contact resistance of 12 mOhms (internal) and 5 mOhms (external), an insulation resistance of 1000 MΩ at DC 500V, and a voltage withstand capability of AC 500V for one minute.

Attenuators Feature Summary

• Provides precise signal attenuation for test board configurations
• Ensures reliable high-frequency performance through gold-plated internal components
• Features durable threaded mechanical connection for secure installation

Attenuators Applications

• Device Under Test (DUT) evaluation boards
• Millimeter-wave measurement port termination
• Signal strength adjustment in RF testing setups

Attenuators Procurement Notes

Verify the specific attenuation value associated with the suffix code during procurement, as the series includes multiple variants. Confirm that the required SMA mating interface matches the system design. Ensure the threaded mounting style is compatible with the intended chassis or panel configuration before finalizing orders.

Attenuators Selection Notes

Select this model when a fixed attenuation value is required for DUT testing rather than a simple load. Compare against other series like HK or HRM if different frequency ranges or interface types are needed. Consider the physical dimensions and mounting requirements relative to available space in the test fixture assembly.

Attenuators Part Context

This part belongs to the H2.4 series of connectors and accessories manufactured by Hirose Electric Co Ltd. The series is specifically engineered for millimeter-wave frequencies, offering robust performance in demanding RF environments. It complements other series such as HK and SMA-compatible options within the manufacturer's portfolio.

Attenuators Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing fixtures using the specified SMA interface and mounting type.
