EMC Thermopad Ween EMC Technologys TVA 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. TVA Thermopads are also well suited for pre-amplified IF circuits.
