Abstract
The present invention relates to a distributed oscillator, and more particularly, to a high frequency distributed oscillator using coupled transmission lines. According to the present invention, coupled transmission lines capable of increasing the frequency selectivity are used as transmission lines. Signal interference occurs among the coupled transmission lines because of mutual approximation. The coupled transmission lines serve as a filter due to the signal interference. A phase noise characteristic can be thus increased.
