Thermopad Temperature Variable Attenuators

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.

Attenuation Values from 1 to 10dB
Wire Bondable Connections Available
Negative & Positive Coefficients of Attenuation Available
Tape and Reel Packaging Available
Space and Military Qualified
Impedance 50 and 75 Ohms
