HFSS를 이용한 T-DMB용 단일소자 공동여파기 구현
Implementation of a T-DMB Single Element Cavity Filter Using HFSS
Abstract
In this study, we design and implement a cavity filter for the Korea T-DMB broadcasting transmitter station and repeater system. HFSS 3 dimensional field simulation tool is used for this study. T-DMB filter has to be high quality factor Q, and cavity filter is applying in T-DMB system due to high handling power. We use HFSS simulation tool for design to obtain exact resonant frequency with easy design. A cavity filter is implemented based on the simulated results, and test results are compared with simulations. Measured resonant frequency and bandwidth are 211.8MHz and 0.1MHz, and correspond with design values.
