Abstract
Spatial power-combining devices with reduced dimensions are disclosed. Spatial power-combining devices are provided that employ a hybrid structure including both a planar splitter/combiner and an antipodal antenna array. Planar splitters may be arranged to divide an input signal while antipodal antenna arrays may be arranged to combine amplified signals. In other applications, the order may be reversed such that antipodal antenna arrays are arranged to divide an input signal while a planar combiner is arranged to combine amplified signals. Advantages of such spatial power-combining devices include reduced size and weight while maintaining suitable performance for operation in desired frequency bands.
Claims25
A spatial power-combining device comprising:
- an input port and an output port;
- a plurality of amplifier assemblies arranged between the input port and the output port, wherein each amplifier assembly of the plurality of amplifier assemblies comprises an amplifier and an output antenna structure coupled with the amplifier, and the plurality of amplifier assemblies is arranged radially around a center axis of the spatial power-combining device;
- and
- a planar signal splitter arranged between the input port and the plurality of amplifier assemblies.
A spatial power-combining device comprising:
- an input port and an output port;
- a plurality of amplifier assemblies arranged between the input port and the output port, wherein each amplifier assembly of the plurality of amplifier assemblies comprises an amplifier and an antenna structure coupled with the amplifier, and the plurality of amplifier assemblies is arranged radially around a center axis of the spatial power-combining device;
- and
- a plurality of fasteners that extend through a flange of the input port or a flange of the output port such that the plurality of fasteners contacts the plurality of amplifier assemblies.
A spatial power-combining device comprising:
- an input port and an output port;
- and
- a plurality of amplifier assemblies arranged between the input port and the output port, wherein each amplifier assembly of the plurality of amplifier assemblies comprises an amplifier and an antenna structure coupled with the amplifier, and the plurality of amplifier assemblies is arranged radially around a center axis of the spatial power-combining device;
- wherein the spatial power-combining device is configured to operate across a frequency range including 4 gigahertz (GHz) and 40 GHz and the spatial power-combining device comprises a length as measured between the input port and the output port that is less than 3 inches.
