초록

본 논문에서는 주기적 접지구조(PAGS)를 이용하여 실리콘 RFIC 반도체 기판상에 다단 임피던 스변환기를 제작 평가하였다. 제작된 임피던스변환기의 면적은 종래의 약 8.7 %인 0.026 $mm^2$이며, 8 ~ 49.5 GHz의 범위에서 양호한 RF특성을 보여주었다.

Using a coplanar waveguide employing periodic ground structure (PGS) on silicon substrate, a highly miniaturized and broadband impedance transformer was developed for application to low impedance matching in broadband. Concretely, the multi-section transformer was designed using Chebyshev polynomials design technique for ultra broadband operation. Its size was 0.026 $m^2$ on silicon substrate, which was 8.7 % of the one fabricated by conventional coplanar waveguide on silicon substrate. The transformer showed a good RF performance over a ultra broadband from 8 - 49.5 GHz.
