Abstract
Abstract A miniature capacitor assembly comprises a plurality of capacitors each having laterally spaced plates embedded in a ceramic block with alternate plates terminating in contact members at opposite ends of the block. The capacitors are disposed in circumferentially spaced radial array inside a conductive ring with a conductive member at the center of the ring. The contact members contact the ring and conductive member respectively so that the capacitors are effectively in parallel with each other. The capacitors have different capacitance values whereby the assembly has an overall attenuation-frequency characteristic which is substantially flat over a range as high as 14 gigahertz.

Claim 1
Independent Claim
117 words
A miniature capacitor assembly comprising a plurality of miniature capacitors, each of said capacitors comprising laterally spaced conductive plates embedded in a ceramic block, and outer and inner contact members respectively joining alternate conductive plates at opposite ends of said block, a conductive cylindrical ring, a conductive member centrally located in said ring, said capacitors being disposed in circumferentially spaced radial array inside said ring with one outer contact member of each capacitor contacting said ring and the inner other contact member of each capacitor contacting said conductive member, so that said capacitors are effectively connected in parallel between said ring and said central conductive member; and a dielectric material means for encapsulating and protecting said capacitors.
Claim 2
Dependent Claim
117 words
A miniature capacitor assembly comprising a plurality of miniature capacitors, each of said capacitors comprising laterally spaced conductive plates embedded in a ceramic block, and outer and inner contact members respectively joining alternate conductive plates at opposite ends of said block, a conductive cylindrical ring, a conductive member centrally located in said ring, said capacitors being disposed in circumferentially spaced radial array inside said ring with one outer contact member of each capacitor contacting said ring and the inner other contact member of each capacitor contacting said conductive member, so that said capacitors are effectively connected in parallel between said ring and said central conductive member; and a dielectric material means for encapsulating and protecting said capacitors.
Claim 3
Dependent Claim
31 words
A capacitor assembly as defined in claim 1, wherein said ring is formed with internal circumferentially spaced flatlands, said outer contact members of said capacitors being respectively juxtaposed to said lands.
Claim 4
Dependent Claim
37 words
A capacitor assembly as defined in claim 1, wherein said central conductive member is polygonal in cross section, with flat outer sides, said inner contact members contacting said flat outer sides respectively of said central conductive member.
Claim 5
Dependent Claim
52 words
A capacitor assembly as defined in claim 1, wherein said central conductive member has an axial hole, and further includes a conductor extending through said hole and electrically coupled to said central conductive member to pass direct current between an external source of power of a direct current and an external load.
Claim 6
Dependent Claim
107 words
A capacitor assembly as defined in claim 1, wherein said capacitors have respectively different numbers of plates, so that said assembly of capacitors has an overall attenuation-frequency characteristic which is substantially uniform in magnitude over a frequency band which is at least as wide as the total bandwidth of the attenuation-frequency characteristics of said individual capacitors, whereby application of a direct current and radiofrequency current between said central conductive member and an external load in a series circuit results in unattenuated passage of said direct current to said load, while said radiofrequency current is effectively bypassed between said ring and said central conductive member via said capacitors.
