MATCHING CIRCUIT, TRANSMITTER, RECEIVER, TRANSCEIVER, AND RADAR APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a matching circuit capable of adjusting arbitrary impedance drift easily with a high degree of accuracy, and a transmitter, a receiver, a transceiver and a radar apparatus having the matching circuits.

SOLUTION: A first transmission line 6 running in a first direction X is provided with a second transmission line 7 running in one second direction Y1 from a first branch section 17 and a third transmission line 8 running in another second direction Y2 from a second branch section 18. The second and third transmission lines 7, 8 are respectively connected with a first and second phase-shift circuits 11, 12 which can adjust phases of reflected electromagnetic waves by applying a voltage.
