Abstract
Abstract The invention concerns micro-circuit arrangements in which two micro-circuits each consisting of an assembly of components and/or micro-strip conductors within individual compartments, are interconnected. In the arrangement provided by the invention the individual compartments have a common wall in which a gap is provided adjacent the ends of a micro-strip conductor in each micro-circuit and a bridge piece is provided to fit into the gap, which bridge piece consists of a block of dielectric material carrying a conductive member which connects with both micro-strip conductors adjacent the gap.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
112 words
A micro-circuit arrangement comprising two micro-circuits each within adjacent individual compartments having a common wall, and wherein a gap is provided in said common wall adjacent the ends of a microstrip conductor in each micro-circuit which are to be connected one to the other and a bridge piece is provided to fit into said gap, said bridge piece consisting of a block of dielectric material carrying a member of conductive material of which, when said bridge piece is fitted into said gap, one end of said conductive member electrically connects with one of said micro-strip conductors and the other end of said conductive member connects with the other of said microstrip conductors.
Claim 2
Dependent Claim
112 words
A micro-circuit arrangement comprising two micro-circuits each within adjacent individual compartments having a common wall, and wherein a gap is provided in said common wall adjacent the ends of a microstrip conductor in each micro-circuit which are to be connected one to the other and a bridge piece is provided to fit into said gap, said bridge piece consisting of a block of dielectric material carrying a member of conductive material of which, when said bridge piece is fitted into said gap, one end of said conductive member electrically connects with one of said micro-strip conductors and the other end of said conductive member connects with the other of said microstrip conductors.
Claim 3
Dependent Claim
59 words
An arrangement as claimed in claim 1 and wherein said conductive member is a blade, one edge of which is provided to contact said two microstrip conductors, said blade having a thickness which is less than the width of a microstrip conductor and a width chosen in dependence upon the characteristic impedance of said microstrip conductors for optimum matching.
Claim 4
Dependent Claim
32 words
An arrangement as claimed in claim 1 and wherein said block is such that its end adjacent the base of said gap is substantially flush with said one edge of said blade.
Claim 5
Dependent Claim
27 words
An arrangement as claimed in claim 1 and wherein a spring blade extending from said common wall is provided to urge said bridge piece into said gap.
Claim 6
Dependent Claim
24 words
An arrangement as claimed in claim 2 and wherein said characteristic impedance is 50 ohms and said blade has a width equal to 0.115".
Claim 7
Dependent Claim
28 words
An arrangement as claimed in claim 1 and wherein said dielectric material of said block is PTFE and the conductive material of said blade is gold plated brass.
Claim 8
Dependent Claim
125 words
A micro-circuit arrangement comprising two micro-circuits each within adjacent individual compartments having a common wall, and wherein a gap is provided in said common wall adjacent the ends of a microstrip conductor in each micro-circuit which are to be connected one to the other and a bridge piece consisting of a block of dielectric material carrying a member of conductive material of which, when said bridge piece is fitted into said gap, one end of said conductive member electrically connects with one of said microstrip conductors, a socket having a conductor, and the other end of said conductive member being connected to said conductor whereby electrical signals may be injected in or removed from said one microstrip conductor in isolation from said other microstrip conductor.
Claim 9
Dependent Claim
125 words
A micro-circuit arrangement comprising two micro-circuits each within adjacent individual compartments having a common wall, and wherein a gap is provided in said common wall adjacent the ends of a microstrip conductor in each micro-circuit which are to be connected one to the other and a bridge piece consisting of a block of dielectric material carrying a member of conductive material of which, when said bridge piece is fitted into said gap, one end of said conductive member electrically connects with one of said microstrip conductors, a socket having a conductor, and the other end of said conductive member being connected to said conductor whereby electrical signals may be injected in or removed from said one microstrip conductor in isolation from said other microstrip conductor.
Claim 10
Dependent Claim
18 words
An arrangement as claimed in claim 7 wherein said conductor is in inner co-axial relationship to said socket.
Claim 11
Dependent Claim
27 words
An arrangement as claimed in claim 7 wherein said dielectric material of said block is PTFE and the conductive material of said blade is gold plated brass.
Claim 12
Dependent Claim
41 words
An arrangement as claimed in claim 1 wherein said common wall is disposed generally normal to said microcircuits, said common wall has a terminal end surface, and said gap opens into each of said compartments and through said terminal end surface.
