Abstract
A Spatial Power Combining Amplifier (SPCA) exhibiting a new concept for the amplification of coherent (e.g., microwave) radiation. A general description of the SPCA a power analysis at various SPCA stages is provided. A successfully tested S-band SPCA example was able to deliver 120 W of power with a gain of 50 dB and 50 percent efficiency.
Claims21
An apparatus, comprising:
- a power divider dividing input power, inputted on the power divider, into a plurality of portions;
- a spatial power combiner;
- and
- amplifiers coupled to the power divider and the spatial power combiner, wherein:
- each amplifier amplifies one of the portions so as to form an amplified output, and
- the spatial power combiner coherently combines the amplified outputs into a combined output.
