Abstract:

An investigation was made of the electric gradients occurring at rounded edges in high-power transmission-line filters. Various types of dissipative filters which were investigated are described including a complete-transfer-coupler filter, and a 2-turn helical rectangular waveguide filter. A 3-cavity narrow-band L-band filter tunable from 1250-1350 mc is described. The measured performance is presented of an Sband waffle-iron filter that has a pass band extending from 2.6 to 4.1 kmc and a stop band with greater than 40 db attenuation extending from 5.3 to 12.5 kmc. A compact multi-aperture sampling technique is also described that can be conveniently used to measure the harmonic power propagating in multi-mode waveguide. Author
