Abstract
Abstract A high-power, X-band microwave burst generator having an input coaxial line feeding a post extending into a waveguide. The center conductor of the coaxial line has a first switching gap therein and the post terminates at an end spaced, by another switching gap, from the interior wall of the waveguide. An RF block is disposed around the post adjacent the first switching gap. The gaps are dimensioned so that energy switched by the first gap can pass the block, but oscillations caused by discharge at the second gap cannot pass the block.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A pulse generator comprising, in combination, a pair of coaxial conductors forming a coaxial line, the inner conductor thereof having a first gap therein between an input section of said inner conductor and an output post; a resonant cavity having a lateral opening therein to which the outer conductor of said coaxial line is connected so that said post extends into said resonant cavity and terminates at a second gap adjacent the inner wall of said resonant cavity, and an RF block positioned around said post adjacent said first gap.
Claim 2
Dependent Claim
