Abstract
This paper presents a wideband and low noise differential yttrium iron garnet (YIG) oscillator. It utilizes a YIG sphere based transmission resonator, which is coupled via two orthogonal pad-to-pad bonds to a fully differential SiGe MMIC. For an optimized design process, the coupled YIG sphere is described by an equivalent circuit, whose elements are determined by 3D EM simulations. Regarding the tuning range and phase noise, the results of the circuit simulation of the entire oscillator are in good agreement with the measurements. The realized YIG oscillator offers a high oscillation frequency with a tuning range from 32GHz to 48GHz. Moreover, it exhibits excellent phase noise of less than -119dBc/Hz at an offset frequency of 100kHz for oscillation frequencies up to 42 GHz.
