Abstract

We have studied the optimal conditions for design and development on the communication device for a bilateral, and it's electrodes for transmitting electric signal are constructed on the $36^{\circ}$ rotated $LiTaO_3$ substrate by evaporating Al-Cu(W 30%) alloy. At first, we manufactured three kind of samples using this method, and selected two samples as similar with frequency, ripple and passband characteristics, and then we connect two samples by series in order to make bilateral devices. As results, we obtained that the electrode structure has better characteristics then the others, when it's width of reflector and electrode are $1{\lambda}/4$, $1{\lambda}/12$ respectively, and it's frequency is approximately 190.3MHz. Near future, I hope to help the manufacture for communication devices for the multi-channel and the duplex filter.

양방향 통신 장치를 설계 및 개발하기 위한 조건을 구하기 위해 $36^{\circ}$ $LiTaO_3$기판 위에 전극을 형성시켰으며, 전극재료로는 Al-Cu(W 30%)를 이용하였다. 이 방법으로 3가지 서로 다른 샘플 전극을 제작했으며, 주파수 특성, 리플특성 및 대역범위가 유사한 두 전극을 선택 후, 직렬로 연결하여 양방향 통신 장치를 만들었다. 직렬 연결한 양방향 장치 특성은 다른 샘플 전극보다 좋은 결과를 얻었으며, 주파수는 대략 190.3MHz로 측정되었으며, 반사기와 전극 폭을 각각 $1{\lambda}/4$, $1{\lambda}/12$로 하였다. 이 결과들을 바탕으로 향후. 다중 채널을 이용한 통신 소자 개발은 물론 듀플렉스 필터 제작에도 도움을 줄 것을 희망한다.
