Abstract
In this paper, an impulse generator for UWB(Ultra Wide-band) technique with great possibility to be adopted as a next generation indoor WLAN(Wireless Local Area Network) has been designed by using SRD(Step Recovery Diode). Design goal is to design an impulse generator with simple structure, low cost, small size, and high performance. The impulse generator satisfied by FCC's regulation ( frequency range: 3.1~10.6 GHz, limit of power level: -41.25 dBm ) has been simulated by using ADS(Advanced Design System) which is the trade name of the Agilent Technologies. The output power of the impulse generator has been explained separately for single and multi band purposes, respectively.
본 논문에서는 차세대 근거리 실내 무선 환경 기술로 채택 가능성이 높은 UWB(Ultra Wideband)기술용 Impulse Generator를 SRD(Step Recovery Diode)를 이용하여 설계하였다. 설계 목표는 단순한 설계 구조와 함께 저가, 소형, 고성능의 Impulse Generator 개발에 있다. 미국의 FCC(Federal Communications Commission)의 기준인 주파수 범위 3.1~10.6 GHz, 출력 제한 레벨 -41.25 dBm을 만족하는 Impulse Generator를 회로 시뮬레이터인 Agilent Technologies사의 ADS를 이용하여 설계, 제작, 측정하였다. 설계된 회로의 출력 신호는 단일밴드용과 멀티밴드용으로 구분하였다.
