CT4458-20

Attenuators Overview

The Cal Test Electronics CT4458-20 is a connectorized SMA fixed attenuator designed for RF applications up to 18 GHz. It provides a nominal attenuation of 20 dB with a 50 Ohm impedance. The component features a male-to-female interface and supports a maximum power rating of 2 Watts. It operates within a temperature range of -55°C to +125°C, ensuring stability in demanding environments.

Attenuators Feature Summary

• Stainless steel body construction for long-life protection
• Low VSWR and flat frequency response characteristics
• High accuracy and repeatability for signal integrity

Attenuators Applications

• Protecting equipment from damaging signal levels
• Lowering voltage in RF test setups
• Dissipating excess power in measurement circuits
• Improving impedance matching in transmission lines

Attenuators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct attenuation value and connector gender configuration. Confirm RoHS compliance status if required by project specifications. Cross-reference the Mouser part number 510-CT4458-20 or Newark availability for supply chain validation prior to final procurement decisions.

Attenuators Selection Notes

Select this model when a 20 dB attenuation value is required at 50 Ohms for frequencies up to 18 GHz. Ensure the application involves male-to-female interconnection needs. Consider the 2W power handling capability relative to the system's maximum output power. Verify that the operating temperature range meets the environmental requirements of the installation site.

Attenuators Part Context

This component belongs to the CT4458 series of connectorized attenuators from Cal Test Electronics. The series offers various attenuation values while maintaining consistent SMA interfaces and 50 Ohm impedance. These units are engineered for reliability in RF testing and measurement systems requiring precise signal reduction.

Attenuators Replacement Considerations

Compatible substitutes include other CT4458 series variants such as the CT4458-30 for different attenuation requirements. Ensure replacement parts maintain the same SMA male-to-female configuration and 18 GHz frequency limit.
