본 발명의 실시 예에 따르면, 방향성 커플러의 격리도를 높여 최적의 임피던스 정합을 수행할 수 있고, 하나의 검출수단을 사용해 임피던스 정합 장치의 생산단가를 낮출 수 있다.
The impedance the impedance matching unit for performing matching between the power amplifier and antenna in accordance with an embodiment of the invention, the said output and a directional coupler for outputting to couple the transmission signal and the reflection signal reflected from the antenna is output from the power amplifier passing the transmission voltage from the transmission signal detection or detector for detecting the reflected voltage from the received reflected signal and a signal of the transmission signal or the reflection signal output from the directional coupler to the detector, and the predetermined other one of the signal and a switch portion and an impedance matching circuit for adjusting the impedance on the basis of the size of the detected voltage and the reflected voltage of the transmission termination impedance.
According to an embodiment of the invention, to increase the isolation of a directional coupler performs an optimum impedance matching, and can use the one of the detecting means to lower the manufacturing cost of the impedance matching device.
