Abstract

In this paper, a double-sided planar balun using Microstrip-to-CPW coupled structure is fabricated and measured. The measured amplitude and phase imbalance are, respectively, less than 0.2 dB and 2.1$^{\circ}$ in a wide frequency range from 2.44 GHz to 4.33 GHz. It is expected that the proposed balun can improved the performance of balanced mixer, amplifier and feeding network of antennas. Also, it can be used in many microwave multilayer structures due to its structural characteristics.

본 논문에서는 마이크로스트립 대 CPW결합 구조를 이용하여 다양한 신호 정합회로에 사용되는 발룬을 제작 측정하였다. 측정 결과, 가용 주파수 2.44~4.33 GHz에서 삽입 손실의 차이는 0.2 dB 이내이고 위상 차이는 2.1$^{\circ}$ 이내로 나타났다. 따라서 제안된 발룬은 구조적 특성으로 인해 다양한 초고주파용 다층 회로에 사용되어 혼합기, 증폭기, 안테나의 급전부 등의 성능향상에 기여할 것으로 기대된다.
