EMC Technology’s TV A Thermopads are microwave
absorbtive attenuators which provide power dissipation
that varies with temperature and operate in frequency
ranges from DC to 6 GHz. This surface mount,
temperature variable attenuator requires no bias or control
voltages and generates zero distortion. TV A Thermopads
are also well suited for pre-amplified IF circuits.
