- W2003538692 abstract "본 논문에서는 초광대역 특성을 가지는 평면형 대역 가변 체배기의 설계 과정을 소개하고 있다. 제안된 체배기에서는 초광대역 마이크로스트립-CPS 전이 구조(발룬)를 입력단의 정합 회로로, 초광대역 마이크로스트립-CPW 전이 구조를 출력단의 정합 회로로 사용하였다. 입력단에 사용된 발룬 구조로 인해 다이오드에 바이어스를 가할 수 있는데, 구현된 체배기의 대역 가변은 다이오드에 인가되는 전압을 가변함으로써 얻을 수 있다. 바이어스 전압이 -0.6 V일 때 체배기의 동작 주파수는 <TEX>$10{sim}20$</TEX> GHz, 인가 전압이 <TEX>$-0.2{sim}-0.4$</TEX> V일 때 동작 주파수는 <TEX>$10{sim}30$</TEX> GHz, 인가 전압이 0 V일 때 동작 주파수는 <TEX>$20{sim}30$</TEX> GHz로 변함을 확인하였다. 또한, 구현된 체배기의 변환 손실은 최대 15 dB 이고, 입력 주파수의 억압 특성은 평균 30 dB 이상이 되는 우수한 특성을 확인하였다. In this paper, design and the implementation method of a band-tunable ultra-wideband planar doubler are described Microstrip-to-CPS(balun) transition and Microstrip-to-CPW transition are respectively used for input/output matching circuits for the doubler. The Input balun structure allows to apply diode bias, and the doubler output frequency is tunable by changing the diode bias voltage. With the bias voltage of -0.6 V, the measured operating frequency band of the implemented doubler is <TEX>$10{sim}20$</TEX> GHz, with the bias voltage of <TEX>$-0.2{sim}-0.4$</TEX> V, the operating frequency band is <TEX>$10{sim}30$</TEX> GHz, and with 0 V bias, the operating frequency band is <TEX>$20{sim}30$</TEX> GHz. The doubler provides conversion loss of less than 15 dB and fundamental frequency suppression of 30 dB." @default.
