CT3369A-20

Attenuators Overview

The CT3369A-20 is a fixed coaxial attenuator from the CT3369A series, manufactured by Cal Test Electronics. It features BNC male-to-female connectors with a nominal impedance of 50 Ohms. The device provides a maximum attenuation of 20 dB with a tolerance of ±0.5 dB and supports a power rating of 2 W. It operates within a frequency range up to 4 GHz. The unit measures 42 mm in length and weighs 32.095 g. Operating temperatures range from -65°C to +125°C.

Attenuators Feature Summary

• Linear passive transmission line component designed for instrument-grade applications.
• Fixed attenuation value ensures consistent signal reduction without variable adjustment.
• Robust mechanical construction suitable for high-temperature environments.

Attenuators Applications

• RF signal level reduction in test and measurement setups.
• Impedance matching between 50 Ohm source and load circuits.
• Protection of sensitive receiver inputs from high-power signals.

Attenuators Procurement Notes

Verify that the required attenuation value matches the specific model suffix, as the CT3369A series includes variants with different dB ratings such as 10 dB or 30 dB. Confirm connector gender compatibility, ensuring the application requires a male-to-female configuration. Check operational temperature limits against environmental conditions. Ensure the power rating of 2 W is sufficient for the intended signal levels to prevent damage. Validate frequency requirements do not exceed the 4 GHz maximum specification.

Attenuators Selection Notes

Select this component when a precise 20 dB reduction is needed at 50 Ohms. Consider the physical dimensions if space constraints exist in the assembly. Evaluate the thermal environment to ensure operation within the specified temperature range. Compare against other series members if different attenuation values are required. Verify connector type compatibility with existing cabling infrastructure.

Attenuators Part Context

This part belongs to the CT3369A series of instrument-grade BNC attenuators. Similar models include CT3369A-10 (10 dB) and CT3369A-30 (30 dB), which share identical connector types, impedance, and physical dimensions but differ in attenuation values and maximum frequency specifications. The series is designed for consistent performance across various RF testing scenarios.
