초록

Ansoft HFSS와 Serenade를 사용하여, 적층형 저역통과필터(LPF)와 RF 다이오드 스위치를 설계하였다. RF diode switch의 등가회로를 참고한 시뮬레이션은 송신모드 (Transmit mode)일 때 다이오드를 인덕터(Inductor)로 등가 회로화 하였고, 수신모드(Receive mode) 일때는 다이오드를 커패시터(Capacitor)로 변환하여 시뮬레이션 하였다. 적측형 RF diode 설계는 소자 와 수축률 변화를 고려하여 수행하였다.

Using Ansoft HFSS(High Frequency Structure Simulator) and Serenade(circuit simulator), multilayer LPF and RF diode switch for GSM were designed. Diodes were transformed the inductor and capacitor in Tx and Rx for the simulation of equivalent circuit, respectively. In particular, the design of the simulation for multilayer RF diode switch was carried out with considering the variance of device and contraction percentage.
