“Rack-Integrated Cavity Combiner for 650 MHz Solid State Power Amplifier with 98.5% Combining Efficiency”

https://pubmed.ncbi.nlm.nih.gov/38117202

The abstract describes the design and testing of a rack-integrated cavity combiner for a 650 MHz solid state power amplifier system, which can combine the output power of 12 modules with high efficiency and adjustability, and has been tested to have a combining efficiency of 98.5%.
