Abstract

In this paper, we designed and fabricated a Ka-band synthesizer module. In addition, the systematic layout procedure and the test procedure were presented for the construction of compact synthesizer. To implement the Ka-band synthesizer, X-band VCO is employed as VCO and its frequency was multiplied by 3 with frequency tripler. The fabricated frequency synthesizer shows a frequency tuning range of 500 MHz, output power of about 14 dBm, and a phase noise of -96.17 dBc/Hz at the 100 kHz offset frequency.

본 논문에서는 복합 소형화된 Ka-대역 주파수 합성기 모듈을 제작하였다. 본 논문을 통하여 소형화 구성시 배치 방법과 체계적인 검증 방법을 제시하였다. 제작된 주파수 합성기는 X-대역 전압 제어 발진기(VCO: Voltage Controlled Oscillator)의 주파수를 3체배하여 구성하였으며, 제작된 모듈은 500 MHz 주파수 가변 범위와 약 14 dBm의 출력 전력, 그리고 100 kHz 오프셋 주파수에서 -96.17 dBc/Hz의 위상 잡음 특성을 보여주고 있다.
