TVA Standard Thermopad®
  EMC Technology’s 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. This product is available with various metallization styles and plating options including RoHS compliant lead free silver over nickel plating, 60/40 low temperature solder plating or 60/40 solder fused finish for easy reflow processing.
