CT3353-03

Attenuators Overview

The CT3353-03 is an instrument-grade RF attenuator manufactured by Cal Test Electronics. It provides a fixed attenuation value of 3 dB with a characteristic impedance of 50 ohms. The device utilizes N-type connectors, specifically configured as male to female. It operates within a frequency range extending up to 12.4 GHz and supports a power handling capacity of 2 watts. The construction features a brass body with nickel plating, gold-plated contacts made of brass and beryllium copper, and PTFE dielectric material.

Attenuators Feature Summary

• Provides precise 3 dB fixed signal attenuation for RF applications
• Ensures reliable performance through gold-plated contact interfaces
• Constructed with durable nickel-plated brass housing
• Utilizes low-loss PTFE dielectric for stable electrical characteristics

Attenuators Applications

• RF test and measurement instrumentation setups
• Signal level adjustment in communication systems
• Laboratory calibration and verification procedures

Attenuators Procurement Notes

Verify the specific connector gender configuration matches the requirement, as product listings may vary between N-type male-to-female and BNC variants under similar model prefixes. Confirm the attenuation value is exactly 3 dB and the frequency range extends to at least 12.4 GHz. Ensure the power rating of 2 watts meets system thermal requirements. Check RoHS compliance status if environmental regulations apply to the deployment environment.

Attenuators Selection Notes

Select this component when a fixed 3 dB reduction is required in a 50-ohm system using N-type interconnects. The instrument-grade classification indicates suitability for precision testing environments where stability and repeatability are critical. Consider the physical size and mounting requirements relative to the available space in the test setup. Verify compatibility with existing cable assemblies and adapter hardware.

Attenuators Part Context

This component belongs to the Cal Test Electronics RF attenuator series, designed for high-performance electronic testing. The CT3353 series typically includes various attenuation values and connector types. This specific model focuses on the N-type interface, distinguishing it from other series members that may use SMA or BNC connectors. It serves as a passive linear device for managing signal power levels without introducing significant distortion.

Attenuators Replacement Considerations

Direct substitutes include other Cal Test Electronics models with identical 3 dB attenuation and N-type connectors, such as variations within the CT3353 family. Cross-brand replacements must match the 50-ohm impedance, 2-watt power rating, and 12.4 GHz frequency limit. Verify mechanical dimensions and connector thread specifications to ensure physical compatibility.
