Abstract
In a microwave apparatus with an air-tight window plate, first and second coaxial waveguide assemblies are coupled to each other so that a coaxial waveguide is formed. The first and second inner conductor sections of the first and second assemblies have first and second metal blocks. The first metal block is fitted in the second metal block by a shinkage fit and the first outer conductor section of the first assembly is air-tightly welded to the second outer conductor section of the second assembly. An RF matching annular groove is defined between the first and second metal blocks.
