Smiths Interconnect|EMC's TVA Thermopads® are microwave absorptive 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. This product is available with various metallization styles and plating options including wire-bondable gold finish, RoHS-compliant lead-free silver over nickel plating, Sn60Pb40 low temperature solder plating, or Sn60Pb40 solder fused finish for easy reflow processing. It is available in both negative and positive temperature coefficient of attenuation (TCA). Thermopads with negative TCA are ideal for amplifier gain compensation over temperature. Thermopads with positive TCA can be used in fault detection and circuit protection applications.
