The chips perform well over a wide frequencyrange, exhibiting low VSWR response from DC to 20 Ghz and terminations allow the chips to be reflowed or hand soldered intomicrowave circuits easily while maintaining excellent return losscharacteristics. Parasitic reactance is very low for these chips withcapacitance being typically less than Artthinfilmhighfrequencychipresistorsare producedwithatantalum-nitridebasedresist orelementthatisextremelystablewithtime,t emperature,andfrequency.
