Abstract
To cancel a reflected wave reflected from a connecting portion () and leaking into a feedback signal when a non-matched component is connected, the reflected wave is extracted by a circulator () and its phase and amplitude are adjusted by a vector adjusting circuit (), and then the thus adjusted reflected wave is vector-summed with the feedback signal in a vector sum circuit ().
