Abstract
A delay line device for delaying signal transmission, comprising a dielectric layer, a grounding electrode layer disposed on one surface of the dielectric layer, a strip line conductor layer disposed on the other surface of the dielectric layer, an input terminal and an output terminal respectively connected to the strip line conductor layer at two positions, and a delay time adjusting electrode connected to at least one of the input and output terminals, a capacitance of which influences a delay time being obtained between the delay time adjusting electrode and the grounding electrode layer. The capacitance of the delay time adjusting electrode is adjustable, thereby permitting adjustment of the delay time.
Claims15
