ABSTRACT:
A circuit assembly may include one or more coupler sections, and may include a phase inverter and/or a phase shifter. A coupler section may include a phase inverter. A coupler may include first and second mutually coupled spirals disposed on opposite sides of a dielectric substrate. Conductors forming the spirals may be opposite each other on the substrate and each spiral may include one or more portions on each side of the substrate. Some circuit assemblies may include first and second multi-port coupler sections. A phase inverter or a phase shifter may be coupled between coupler sections. In some examples, a circuit assembly may include first and second conductors each having first and second ends and mutually inductively coupled turns, and a capacitive device coupling the first ends of the first and second conductors to a reference potential.
