Design of state of art low noise VCO using MMIC negative resistance modules

In this paper we present the design, fabrication and measurement of a state of the art low noise 10 GHz MESFET VCO. The novel design method associated with modern CAD. tools yield oscillators with an excellent phase noise of -90 dBc/Hz at an offset of 100KHz, which is the best result published for a X band FET VCO, with an electrical tuning range of 10%. The output power of 15 dBm over the oscillation frequency range is obtained
