EMC Technology - ETVA - EMC Technology’s ETVA Thermopads are microwave absorbtive attenuators which provide power dissipation that varies with temperature and operate in frequency ranges from DC to 3 GHz. The ETVA offers extended shift achieving greater temperature compensation. 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 RoHS compliant lead free silver over nickel plating, 60/40 low temperature solder plating or 60/40 solder fused finish for easy reflow processing.
