する可変遅延線装置。[Claims for Utility Model Registration] An impedance line is connected to the input point of a variable delay line in which variable capacitance diodes are connected to inductance elements in a ladder shape, and the output point of the variable delay line is set to have the same characteristic impedance as the variable delay line. In the variable delay line device configured to change the delay time of the variable delay line by changing the control voltage applied to the variable capacitance diode, the characteristic impedance of the variable delay line is equal to the impedance. A matching resistor is selected to be larger than the characteristic impedance of the line, is connected in parallel to the impedance line together with the variable delay line, and has a resistance value such that a combined value with the characteristic impedance of the variable delay line matches the impedance line. , a variable delay line device connected to the input point.
