Disclosed is a circuit. According to one embodiment of the present invention, the circuit includes two or more RF channels, wherein each of the channels includes an input node, a phase shifter, and an output node and each of the channels is configured to receive an RF oscillator signal at an input node and to provide an RF output signal at an output node; an RF combiner circuit configured to be connected with the output of the RF channel and to generate a combined signal representing the combination of the RF output signal; and a monitor circuit configured to include a mixer, to receive the combined signal, and to down convert the combined signal using an RF reference signal. Accordingly, a mixer output signal depending on a phase of the RF output signal is generated. 여기에 회로가 설명된다. 일실시예에 따르면, 회로는 2 이상의 RF 채널을 포함하고, 각각의 채널은 입력 노드, 위상 시프터, 출력 노드를 포함한다. 각각의 채널은 입력 노드에서 RF 발진기 신호를 수신하고 출력 노드에서 RF 출력 신호를 제공하도록 구성된다. 회로는 RF 채널의 출력과 연결되고, RF 출력 신호의 결합을 나타내는 결합된 신호를 생성하도록 구성된 RF 결합기 회로와, 믹서를 포함하고, 결합된 신호를 수신하고 RF 기준 신호를 이용하여 결합된 신호를 다운 변환하도록 구성된 모니터 회로를 더 포함한다. 따라서, RF 출력 신호의 위상에 의존하는 믹서 출력 신호가 생성된다.
