ABSTRACT:
A three dimensional (3D) microwave monolithic integrated circuit (MMIC) multi-push voltage controlled oscillator (VCO) and methods of making the same is provided. The 3D MMIC multi-push oscillator includes a plurality of matching frequency oscillators coupled to a phasing ring in substantially equidistantly spaced apart locations. A combined VCO output signal is provided at a central output connection point of the phasing ring. The central output connection point resides on a first plane. An output conductor transition has a first end coupled to the central output connection point and a second end provided as an output to the quad-push VCO. The output conductor transition extends transverse to the first plane and terminates at a second plane separated from the first plane. The multi-push oscillator can be a push-push, quad-push or N-push type VCO based on a particular implementation.
