摘要： Antenna waveguide transitions for solid state power amplifiers (SSPAs) are disclosed. An SSPA includes a waveguide channel that is configured to propagate an input signal, such as an electromagnetic signal, from an input port to a solid state amplifier for amplification. The waveguide channel is further configured to propagate an amplified signal from the solid state amplifier to an output port. Waveguide transitions to and from the solid state amplifier are bandwidth matched to the waveguide channel. Additionally, the waveguide transitions may be thermally coupled to the waveguide channel. The waveguide transitions may include antenna structures that have a signal conductor and a ground conductor. In this manner, the SSPA may have improved broadband coupling as well as improved thermal dissipation for heat generated by the solid state amplifier.

摘要： Antenna structures for spatial power-combining devices are disclosed. A spatial power-combining device includes a plurality of amplifier assemblies, and each amplifier assembly includes an amplifier coupled between an input antenna and an output antenna. At least one of the input antenna or the output antenna comprises a nonlinear shape that is configured to propagate a signal along a nonlinear path to or from the amplifier with reduced signal loss. Accordingly, each amplifier may be configured on a corresponding amplifier assembly in a position such that each amplifier is spaced farther apart from other amplifiers in the spatial power-combining device. In this manner, heat generated by the amplifiers may be more evenly dissipated by the spatial power-combining device.

摘要： Monolithic microwave integrated circuits (MMICs) with phase tuning are disclosed. A MMIC structure may include a MMIC amplifier with electrically coupled input and output lines. The MMIC structure may further include an adjustable cover over the MMIC amplifier that includes at least one portion that can be adjusted closer to or farther away from either the input or output lines. In this manner, a signal capacitance between the adjustable cover and the input or output lines is adjustable, and accordingly, a signal phase of the MMIC structure may be tuned. A spatial power-combining device may include a plurality of amplifier assemblies, wherein each amplifier assembly includes a MMIC amplifier with an adjustable cover. In this manner, the plurality of amplifier assemblies may be phase-tuned to a target value.

摘要： Spatial power-combining devices and, in particular, spatial power-combining devices with filtering elements are disclosed. A spatial power-combining device includes a plurality of amplifier assemblies and each amplifier assembly includes an input antenna structure, an amplifier, an output antenna structure, and a filtering element. A filtering element may be an integral single component with an input signal conductor of the input antenna structure or an integral single component with an output signal conductor of the output antenna structure. In some aspects, a filtering element may be an integral single component with both the input signal conductor and the output signal conductor.
