Attenuators Procurement Notes

Verify the specific connector gender configuration required for your system integration, as this model utilizes a female-to-female interface. Confirm that the operational power levels do not exceed the 300 Watt rating to prevent component damage. Ensure the operating frequency remains within the specified DC to 3 GHz range for optimal performance. Check for any environmental constraints regarding the heatsink body dimensions during installation.

Attenuators Selection Notes

Select this attenuator when a high-power fixed loss is required in the lower microwave frequency band. The 50 dB value is suitable for significant signal reduction tasks. Consider the TNC interface compatibility with existing cabling infrastructure. The heatsink design makes it appropriate for environments where thermal management is critical due to high power dissipation.
