Design and implementation of an L-band voltage controlled oscillator

Abstract

This thesis has known the proposition of a microwave device that is a voltage controlled oscillator for L-band applications, the document included four chapters in which we have discussed various microwave VCO technologies, their principle of operation, simulation and its results, and finally the realization of the device using microstrip transmission lines and Surface Mounted Device SMD components, a discussion took place to compare simulation to measurement results. The proposed VCO operates from 1GHz up to 1:65GHz, that is a band with high immunity to atmospheric attenuation which makes it suitable for Long range radar systems
