Abstract
Abstract A microwave switch including a microstrip circuit having a plurality of strip conductors disposed on a planar surface of a dielectric substrate, a plurality of diodes having first electrodes connected to corresponding ones of the strip conductors, and a feed line disposed in a plane different from the planar surface of the substrate and connected to a second electrode of the diodes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A microwave device, comprising: a. a microstrip circuit including a plurality of strip conductors disposed on a planar surface of a dielectric substrate, such strip conductors extending radially from an axis perpendicular to the plane of the substrate, such circuit being toroidal and symmetrically disposed about such axis; b. a toroidal semiconductor body having a plurality of mesa shaped diodes and first electrodes formed on top regions of corresponding ones of the diodes, such semiconductor body being disposed symmetrically about the axis, each one of the first electrodes being directly bonded to a corresponding one of the strip conductors; and c. a feed line disposed coaxially with the axis and passing through center regions of the microstrip circuit and the semiconductor body, such feed line being electrically connected to a second electrode of the diodes.
Claim 2
Dependent Claim
135 words
A microwave device, comprising: a. a microstrip circuit including a plurality of strip conductors disposed on a planar surface of a dielectric substrate, such strip conductors extending radially from an axis perpendicular to the plane of the substrate, such circuit being toroidal and symmetrically disposed about such axis; b. a toroidal semiconductor body having a plurality of mesa shaped diodes and first electrodes formed on top regions of corresponding ones of the diodes, such semiconductor body being disposed symmetrically about the axis, each one of the first electrodes being directly bonded to a corresponding one of the strip conductors; and c. a feed line disposed coaxially with the axis and passing through center regions of the microstrip circuit and the semiconductor body, such feed line being electrically connected to a second electrode of the diodes.
Claim 3
Dependent Claim
32 words
The microwave device recited in claim 1 including a feedthrough having an outer conductor connected to a ground plane of the microstrip circuit and wherein the feed line passes through the feedthrough.
Claim 4
Dependent Claim
15 words
The microwave device recited in claim 1 wherein the microstrip circuit includes an alumina substrate.
Claim 5
Dependent Claim
39 words
The microstrip device recited in claim 1 wherein the mesa shaped diodes are formed on one surface of the semiconductor body and the second electrode is formed as a common electrode of an opposite surface of such semiconductor body.
Claim 6
Dependent Claim
