The Thermopad
®
is a patented (Patent # 5,332,981), absorptive microwave attenuator, which provides power
dissipation that varies with temperature. The device can be used in any application that requires a known amount of
attenuation change for a particular temperature shift. This is particularly useful for maintaining constant gain in
amplifiers, mixers, power dividers, and other signal processing components over temperature.
In applications from DC-46 GHz, EMC’s Thermopad
®
is the ideal temperature compensation solution for cost,
performance, and reliability. The Thermopad
®
can replace closed loop temperature compensation circuits with a
single chip device requiring no bias or control. It excels in applications involving multiple tones and complex
modulation schemes such as cellular base station applications to radar because of its low cost and because it
produces no signal distortion.
In high reliability, military, and spacecraft applications, the Thermopad
®
reduces system complexity and cost while
improving overall reliability. The Thermopad
®
is available in a wide variety of package styles. Most styles are available
in tape and reel packaging.
