Thermopad® Temperature Variable Attenuators

EMC Technology is the world leader in temperature variable attenuators from DC through Q band, featuring our patented Thermopad line of products which compensate for gain variation over temperature. The Thermopad® (Patent # 5,332,981) is a totally passive, surface mountable temperature variable attenuator. It requires no bias or control voltages and does not generate distortion. The Thermopad can be used in place of a standard chip attenuator to combine level setting or buffering and temperature compensation in a single chip design. This will reduce component count, increase reliability, and lower costs. Applications include power amplifiers, mixers, MMIC amplifiers, directional couplers and diode detectors.
