Title:

DISTRIBUTED CIRCUIT AND CONTROL METHOD FOR SAME

Document Type and Number:

WIPO Patent Application WO/2022/176187

Kind Code:

A1

Abstract:

The distributed circuit (10) according to the present invention is provided with a first transmission line (121) having an input end into which an input signal is input, a second transmission line (122) having an output end from which an output signal is output, a plurality of unit cells arranged along the first and second transmission lines (121, 122) and having input terminals connected to the first transmission line (121) and output terminals connected to the second transmission line (122), two input end resistors (13_1, 13_2) connected in parallel to the end of the first transmission line (121), and two output end resistors (14_1, 14_2) connected in parallel to the end of the second transmission line (122). At least one input end resistor is a temperature gradient resistor, at least one output end resistor is a temperature gradient resistor, the voltage at the two input end resistors (13_1, 13_2) is symmetrically changed, and the voltage at the two output end resistors (14_1, 14_2) is symmetrically changed.　Thus, the distributed circuit according to the present invention is able to easily adjust the end resistors and can thereby provide excellent frequency characteristics.
