A Study on the Design and Implementation of Ku-Band Frequency Synthesizer by using PLL
PLL을 이용한 Ku-Band 주파수 합성기 설계 및 제작에 관한 연구
Abstract
The design and implementation of Ku-Band frequency synthesizer was accomplished by the use of PLL and frquency multiple method. Design procedure and operation characteristics of PLL circuit were analyzed on the basis of control theory to synthesize about 1 GHz frequency which should be stable. By connecting frequency doubler and frequency eighth multiplier to the designed PLL circuit in series, Ku-Band frequency was synthesized. The validity of design method of Ku-Band frequency synthesizer was verified through experimental results.
Ku-Band주파수 합성기를 PLL과 주파수 체배 방법을 이용하여 설계 및 제작하였다. 안정된 약 1 GHz의 주파수를 합성하기 위해 PLL 회로의 설계 과정 및 동작 특성을 제어이론을 바탕으로 고찰하였다. 안정된 약 1 GHz PLL 회로에 주파수 2 체배기, 주파수 8 체배기를 연결하여 Ku-Band 주파수를 합성하였다. 실험결과를 통하여 Ku-Band 주파수 합성기 설계 방법의 타당성을 확인하였다.
