This document describes techniques and systems for a vertical microstrip-to-waveguide transition. A radar system may include a monolithic microwave integrated circuit (MIMIC) to generate electromagnetic signals and a printed circuit board (PCB) that includes a first surface, a microstrip, and a grounding pattern. The microstrip can be located on the first surface and operatively connect to the MIMIC. The grounding pattern is located on the first surface and made of conductive material. The radar system also includes a transition channel positioned over the grounding pattern, which includes a vertical taper between a bottom surface and a top surface. The transition channel defines a dielectric-filled portion formed by the grounding pattern and its interior surface. The described vertical transition can reduce manufacturing costs and support a wide bandwidth by tolerating an air gap at the transition-to-waveguide interface.

An electronic switch includes a substrate and a rotator assembly. The rotator assembly is configured to prevent rotation between a first rotational configuration and a second rotational configuration in a first translational position of the rotator assembly, while the rotator assembly is configured to rotate between the first rotational configuration and the second rotational configuration in a second translational position of the rotator assembly. The second translational position of the rotator assembly is translationally offset from the first translational position of the rotator assembly. An electrical contact of the rotator assembly is configured to electrically connect an electronic input path of the substrate to an electronic output path of the substrate in the first rotational configuration and first translational position of the rotator assembly, but not to electrically connect the electronic input path to the electronic output path in the second rotational configuration of the rotator assembly or in the second translational position of the rotator assembly.
