4778-20

Attenuators Overview

The L3 Narda-MITEQ 4778-20 is a fixed RF attenuator module designed for signal level reduction in radio frequency circuits. It provides a nominal attenuation of 20 dB with a tolerance of +/- 0.3 dB. The device operates across a frequency range from 0 Hz to 12.4 GHz and supports a maximum average input power of 2.0 Watts. It utilizes SMA connectors and is housed in an in-line module package configuration, ensuring reliable performance in high-frequency applications.

Attenuators Feature Summary

• Provides precise 20 dB signal attenuation with tight tolerance
• Operates effectively from DC up to 12.4 GHz
• Handles 2.0 Watts average input power
• Features SMA connector interface for direct integration

Attenuators Applications

• RF test and measurement equipment
• Wireless communication systems
• Signal conditioning in microwave circuits

Attenuators Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the SMA connector type matches your system requirements. Ensure the operating environment stays within the specified 2.0 W average power limit to prevent damage. Check for any lead-free certification documentation if required by your assembly process.

Attenuators Selection Notes

Select this component when a fixed 20 dB attenuation is required at frequencies up to 12.4 GHz. Consider the 2.0 W power handling capability against your system's peak and average power levels. The SMA interface dictates connector compatibility with existing PCBs or cable assemblies. Evaluate thermal management needs given the power dissipation characteristics of the module.

Attenuators Part Context

This part belongs to the L3 Narda-MITEQ family of fixed attenuators. It is distinct from variable attenuators and other attenuation values within the same series. The 4778-20 specifically addresses the need for stable, low-reflection signal reduction in broadband RF environments using standard SMA interfaces.
