<p>There are disclosed an automatic microwave impedance adjusting apparatus for a microwave load (30) connected to a microwave oscillator (10) through a microwave transmission line (13), and an automatic microwave impedance adjusting method therefor. In the apparatus and method, there is measured either an impedance seen looking toward a microwave load (30) at a predetermined reference point of a microwave transmission line (13) connected between a microwave oscillator (10) and the microwave load (30) or a reflection coefficient thereat by detecting a voltage standing wave of a microwave propagating on the microwave transmission line (13). Thereafter, a controller (10C) controls variable impedance means (31) mounted on the microwave load side of the reference point on the microwave transmission line (13) responsive to the value measured at the first step, so as to adjust the impedance seen looking toward the microwave load (30) to a predetermined value.</p> |
