2.46 GHz solid-state high-power oscillator with planar cavity resonator

In this paper, we have studied a high power oscillator of a high RF output power and a good phase noise. We designed the high power oscillator using LDMOS(laterally diffused metal oxide semiconductor) device by the use of an Agilent advanced design system (ADS). We also designed the rectangular cavity resonator in order to obtain a good phase noise by using a 3-D high frequency structure simulator (HFSS) code. In Section II, the simulation and measurement results of the planar cavity resonator (PCR) were described. In section III, the output characteristics of a high power oscillator using PCR was described.
