The temperature variable attenuator Thermopad® from EMC Technology, a Smiths Interconnect company, now comes in a coaxial package.
The coaxial TVA version of the Thermopad® product line offers the same benefits as the 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 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/°C.
The coaxial Thermopad is designed for an operating temperature range of -55 up to +150°C. It features a power rating of 2.0 Watts and power derating is 100% at 125°C, derating to 0% at 150°C.
