4778-30

Attenuators Overview

The L3 Narda-MITEQ 4778-30 is a fixed RF attenuator module designed for signal level reduction in radio frequency systems. It provides a nominal attenuation of 30 dB with a tolerance of ±0.8 dB. The device operates within a frequency range of DC to 6 GHz and supports a maximum average power input of 2 Watts. It features SMA connectors in a male-to-female configuration, housed in an inline module package suitable for PCB or panel mounting.

Attenuators Feature Summary

• Provides precise 30 dB signal attenuation for RF circuit applications
• Operates effectively from DC up to 6 GHz frequency range
• Handles up to 2 Watts of average power input
• Utilizes standard SMA connector interface for easy integration

Attenuators Applications

• RF test and measurement equipment signal conditioning
• Communication system power level adjustment
• Receiver input protection and impedance matching
• Laboratory benchtop instrumentation signal scaling

Attenuators Procurement Notes

Verify the specific datasheet version for the 4778-30 model to confirm exact mechanical dimensions and connector gender specifications. Ensure that the operating environment does not exceed the 2W average power rating or the 6 GHz frequency limit. Cross-reference the manufacturer part number with authorized distributors to guarantee component authenticity and traceability.

Attenuators Selection Notes

Select this component when a fixed 30 dB attenuation value is required within a 6 GHz bandwidth. Consider the SMA interface compatibility with existing system connectors. Evaluate the 2W power handling capability against peak and average signal levels in the application path to ensure reliable operation without thermal degradation.

Attenuators Part Context

This component belongs to the Narda-MITEQ 477 series of miniature fixed attenuators. The series offers various attenuation values ranging from 3 dB to 30 dB, all sharing similar compact form factors and SMA connectivity options. These modules are engineered for consistent performance across wide frequency bands in professional RF environments.

Attenuators Replacement Considerations

Direct substitutes include other 30 dB fixed attenuators from the same 477 series family if available. Verify that any replacement maintains the SMA (M/F) interface and matches the 2W power rating. Ensure the frequency response remains adequate for DC to 6 GHz operations.
