Temperature Variable Attenuator comes in coaxial package.

Press Release Summary:

Thermopad® Coaxial TVA attenuators feature SMA male-to-SMA female interface and nominal impedance of 50 ohm. Able to cover dc to 6 GHz frequency range, devices exhibit VSWR of 1.35 at 1 GHz, attenuation accuracy of ±0.5 dB, and TCA tolerance of ±0.001 dB/dB/ºC. Products have operating temperature range of -55 to +150°C and feature 2.0 W power rating. Power derating is 100% at 125ºC, derating to 0% at 150ºC.

Original Press Release:

Popular Temperature Variable Attenuator now Comes in a Coaxial Package

The popular temperature variable attenuator Thermopad® from EMC Technology, a Smiths Interconnect company, now comes in a coaxial package. The new coaxial TVA version of the Thermopad® product line offers the same benefits as the popular standard temperature variable attenuator (cost-effective, high-performance and very reliable) but with the added benefit of a SMA male to SMA female interface.

Thermopad® Coaxial TVA attenuators feature a nominal impedance of 50 Ohms and cover the DC to 6 GHz frequency range. The new devices benefit from very low VSWR of 1.35 at 1 GHz, a high attenuation accuracy of ±0.5dB and a TCA tolerance of ±0.001dB/dB/ºC.

The coaxial Thermopad® is designed for an operating temperature range of -55 up to +150 degrees Celsius. It features a power rating of 2.0 Watts and power derating is 100 percent at 125 degrees Celsius, derating to 0 percent at 150 degrees Celsius.
