종단 가변 Comb-line 필터를 사용한 위상 변위기 설계
A design of the phase shifter using tunable shorted terminated combline filters
초록
In this paper, a design technique is introduced for designing a 360-degree linear analog phase shifter at 1.8㎓. Using tunable short-circuit terminated comb-line filters as reactive loads, the circuit gives a very small insertion loss(less than 0.1㏈) and an almost linear phase shifter over the filter bandwidth for the full 360-degree range. We were showed large phase variation with small capacitance variation in the quadrature hybrid coupler using tunable shorted terminated combline filters.
