A Novel Frequency Doubler Using a Feedforward Structure and DGS Microstrip for Fundamental and High Order Components Suppression

A novel design of a frequency doubler, using a feedforward technique and a defected ground structure (DGS), is described. In the proposed frequency doubler, the feedforward loop suppresses the fundamental component (fo), and the DGS attenuates the high...
The demand for a signal source with high stability and low phase noise increases in microwaves, millimeter-wave communications and radar systems. High frequency signal sources can easily be obtained by multiplying low frequency signals that have relatively high stability and low phase noise. In general, however, frequency multipliers include...
