초록

본 논문에서는 멤스 기술의 하나인 연성 인쇄 회로 기판을 이용하여 임의의 형태로 변형이 가능한 초고주파 멤스 송신기를 제안하였다. 연성 인쇄 회로 기판은 그 무게가 가볍고 두께가 얇아 경량 소형화 모듈을 만드는데 유리한 장점이 있다. 또한, 연성 인쇄 회로 기판은 종이와 같이 유연한 특성을 가지고 있어 평면이 아닌 임의의 곡면 등에 실장할 수 있는 장정을 가지고 있다. 본 논문에서는 근거리 센서 네트워크 구성을 위한 직교 주파수 분할 다중 전송 방식을 위한 선형 무선 송신기를 설계 제작하였다. 송신 모듈의 능동 회로는 전력효율이 높고 선형성이 우수하여 전력 증폭기에 많이 사용되고 있는 InGaP/GaAs HBT 공정을 사용하여 설계 및 제작하였으며, 매칭 회로 및 필터 등의 수동 회로는 연성 인쇄 회로 기판에 직접 집적화 하여 제작하였다. 제작된 멤스 송신기는 EVM 특성을 통하여 시스템 성능을 분석하였다.

This paper presents the flexible MEMS transmitter based on flexible printed circuit board or FPCB, which can be transformed to arbitrary shape. The FPCB is suitable to fabricate light weight and small size modules with the help of its thin thickness. Moreover a module based on FPCB can be attached on the arbitrary curved surface due to its flexible enough to be lolled up like paper. In this paper, the flexible MEMS transmitter integrated on FPCB for a short-distance sensor network which is based on orthogonal frequency division multiplexing(OFDM) communication system is proposed. The active device of the proposed flexible MEMS transmitter is fabricated on InGaP/GaAs HBT process which has been used for power amplifier design to take advantages of high linear and high efficient characteristics. Moreover, the passive devices such as the filter and signal lines are integrated and fabricated on the FPCB board. The performance of the fabricated flexible MEMS transmitter is analyzed with EVM characteristics of the output signal.
