Abstract

An engineering model VCO with a good phase noise for Ku-band satellite transponder is designed using a nonlinear design methodology. It generates frequencies from 1,745 and 1,755 MHz with control voltages from 0 to 5 V DC. This unit requires 7 mA of current from 5 V DC supply voltage. Phase noise characteristics of the manufactured VCO exhibit -114 dBc/Hz @10 kHz offset and -131 dBc/Hz @100 kHz of offset and its output power is 5 dBm.

본 논문에서는 Ku 대역 위성중계기에 사용되는 저위상잡음 특성을 갖는 Engineering Model 전압제어 발진기를 비선형 설계방법으로 설계하였다. 제작한 발진기의 주파수는 1~5 V의 제어전압으로 1.745~1.577MHz의 발진범위를 갖는다. 공급전력은 5V, 6.9mA를 요구한다. 제작한 발진기의 위상잡음은 -114 dBc/Hz ＠10kHz offset, -131 dBc/hz ＠100kHz offsetf을 갖고 출력전력으로 5 dBm을 얻었다.
