Attenuators Procurement Notes

Verify the specific datasheet revision and connector gender compatibility before integration. Confirm that the operating environment remains within the specified 2-watt power limit to prevent thermal damage. Ensure that the required attenuation tolerance aligns with system design margins. Check for any specific packaging or handling requirements detailed in the manufacturer's documentation to maintain component integrity during installation.

Attenuators Selection Notes

Select this model when a stable 30 dB reduction is required across a wide bandwidth up to 18 GHz. Consider the Type-N interface for standard coaxial connections. Evaluate the 2-watt power rating against peak signal levels. Compare VSWR specifications if phase linearity is critical. This component suits applications needing precise, passive signal control without active power sources.

Attenuators Part Context

This component belongs to the Miteq 779 series of fixed precision coaxial attenuators. The series offers various attenuation values including 4, 6, 10, 20, and 40 dB options. All models share similar construction qualities, supporting DC to 18 GHz operation with 2-watt power ratings. The 779-30 specifically addresses needs for significant signal reduction while maintaining high-frequency performance and low reflection characteristics in microwave circuits.

Attenuators Replacement Considerations

Direct substitutes within the same series include the 779-20 (20 dB) and 779-40 (40 dB) for different attenuation needs. Cross-brand equivalents must match the 50-ohm impedance, Type-N interface, and 18 GHz frequency limit. Verify that alternative components meet the ±0.8 dB tolerance and 2-watt power handling requirements to ensure functional parity.
