Abstract: Embodiments of a multiple-path amplifier (e.g., a Doherty amplifier) and a module housing the amplifier include a first amplifier (or first power transistor die) with a first output terminal, a second amplifier (or second power transistor die) with a second output terminal, and an impedance inverter line assembly electrically connected between the first and second output terminals. The impedance inverter line assembly includes a first transmission line and a surface mount component connected in series between the first and second output terminals. In various embodiments, the surface mount component is selected from a fixed-value capacitor, a fixed-value inductor, a tunable capacitor, a tunable inductor, and a tunable passive component network.

Abstract: A circulator-coupler device includes a ferrite element, a resonator over and aligned along an axis with the ferrite element, and a plurality of resonator ports connected to the resonator. The plurality of resonator ports includes first and second resonator ports, and a first portion of a perimeter of the resonator extends between the first and second resonator ports. The circulator further includes a coupler element positioned across a gap from the first portion of the perimeter of the resonator, and a coupler port connected to the coupler element. The device also may include a permanent magnet aligned along the axis with the ferrite element, where the permanent magnet biases the ferrite element and causes a signal conducted through the resonator to have a directionality along a rotational direction that extends from the first resonator port to the second resonator port.

Abstract: A reference circuit includes an integrated circuit (IC) formed on a semiconductor substrate including a first spiral inductor and a second spiral inductor. The first spiral inductor is formed from a first metal layer over the substrate. The second spiral inductor is formed from a second metal layer. The second spiral inductor is offset from the first spiral inductor and includes a first portion overlapping the first spiral inductor. A first capacitor includes a first terminal coupled to receive a radio frequency (RF) signal and a second terminal coupled to a first terminal of the first spiral inductor, and second capacitor includes a first terminal coupled to a second terminal of the first spiral inductor.
