There are three major performance differences between waveguide and coaxial cable: 1) Frequency range: waveguide is suitable for high frequency bands above 30GHz, while coaxial cable is commonly used below 18GHz; 2) Loss: coaxial cable has greater loss at high frequencies (such as RG-405 reaching 0.5dB/m at 10GHz), and waveguide has lower loss (<0.1dB/m); 3) […]

Three effective methods for testing waveguide components include: 1) using a vector network analyzer (VNA) to measure S parameters, ensuring that the frequency range covers 26.5 GHz to 40 GHz; 2) performing a standing wave ratio (VSWR) test with a value of less than 1.5:1; and 3) implementing a power handling capability test, applying a
