  • Patent number: 10340574
    Abstract: A spatial power-combining device and an antenna structure designed for high efficiency, high frequency, and ultra-wide bandwidth operation. The antenna structure may include a signal conductor and a ground conductor that are entirely separated by air. A spatial power-combining device may include a plurality of amplifier assemblies including multiple output antenna structures and an output coaxial waveguide section configured to concurrently combine signals received from each output antenna structure of the plurality of amplifier assemblies. The plurality of amplifier assemblies may also include multiple input antenna structures and an input coaxial waveguide configured to provide an input signal concurrently to each input antenna structure of the plurality of amplifier assemblies.

  • Publication number: 20190068141
    Abstract: 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.

  • Publication number: 20190068123
    Abstract: 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.
