Thermopad®

Temperature Variable Attenuators

Smiths Interconnect Thermopad® products are a totally passive, easy to implement solution for gain compensation designed specifically for demanding high reliability applications.

Features & Benefits

Smiths Interconnect is the world leader in temperature variable attenuators from DC through Ka 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.

  • Wire Bondable Connections Available
  • Negative & Positive Coefficients of Attenuation Available
  • Tape and Reel Packaging Available
  • Space and Military Qualified
