  • Local oscilator distribution and phase shifting circuits
    Patent number: 10187070
    Abstract: Electronic devices, local oscillator circuits, and methods for operating local oscillators are disclosed herein. In one embodiment, a local oscillator circuit includes a first transistor and a second transistor individually having a base, a collector, and an emitter and a transformer having a first transformer inductor magnetically coupled to a second transformer inductor. The first transformer inductor couples the collector of the first transistor to the base of the second transistor. The second transformer inductor couples the collector of the second transistor to the base of the first transistor.
    Type: Grant
