Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
An arrangement to eliminate multipacting in radio frequency (RF) devices disposed in a vacuum-like environment comprising: a RF device disposed in said environment, said device having two RF electrodes capable of supporting multipacting in a RF high voltage region therebetween; and a dielectric material having a given dielectric constant and a given dielectric strength disposed between said two electrodes in at least said region to eliminate multipacting, said dielectric material completely filling said region; said environment is space; and said RF device including a microwave filter having a cavity with a cavity wall providing one of said two electrodes and a plurality of resonators providing the other of said two electrodes; and said dielectric material fills said cavity.
Claim 2
Dependent Claim
118 words
An arrangement to eliminate multipacting in radio frequency (RF) devices disposed in a vacuum-like environment comprising: a RF device disposed in said environment, said device having two RF electrodes capable of supporting multipacting in a RF high voltage region therebetween; and a dielectric material having a given dielectric constant and a given dielectric strength disposed between said two electrodes in at least said region to eliminate multipacting, said dielectric material completely filling said region; said environment is space; and said RF device including a microwave filter having a cavity with a cavity wall providing one of said two electrodes and a plurality of resonators providing the other of said two electrodes; and said dielectric material fills said cavity.
Claim 3
Dependent Claim
14 words
An arrangement according to claim 1, wherein said plurality of resonators are interdigital resonators.
Claim 4
Dependent Claim
113 words
