Abstract
Abstract A microwave circuit and housing in which the housing cavity is reduced in size by providing threaded slots in side walls of the housing which receive tabs extending from the microwave circuit carriers. Pillars are inserted in the slots for maintaining the carriers in position on the bottom surface of the housing and for filling the slots. Reduced weight, height, and width is achieved with a reduced number of piece parts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
A microwave circuit and housing comprising a housing having a bottom surface and opposing side walls and end walls, a cover for said housing, a plurality of slots in said opposing side walls, said slots being parallel to said side walls and running from one edge to an opposing edge of each side wall, at least one microwave circuit including a substrate having a plurality of tabs extending therefrom, said substrate positioned on said bottom surface with said tabs extending into said slots in said opposing side walls, and pillars engaging and filling said slots and engaging said tabs.
Claim 2
Dependent Claim
99 words
A microwave circuit and housing comprising a housing having a bottom surface and opposing side walls and end walls, a cover for said housing, a plurality of slots in said opposing side walls, said slots being parallel to said side walls and running from one edge to an opposing edge of each side wall, at least one microwave circuit including a substrate having a plurality of tabs extending therefrom, said substrate positioned on said bottom surface with said tabs extending into said slots in said opposing side walls, and pillars engaging and filling said slots and engaging said tabs.
Claim 3
Dependent Claim
55 words
The microwave circuit and housing as defined by claim 1 wherein said at least one microwave circuit includes a ceramic substrate with a hybrid circuit formed on at least one major surface thereof, a carrier with the opposite major surface of said ceramic substrate affixed to said carrier, said carrier having said plurality of tabs.
Claim 4
Dependent Claim
25 words
The microwave circuit and housing as defined by claim 2 and including a plurality of microwave circuits and means interconnecting said plurality of microwave circuits.
Claim 5
Dependent Claim
36 words
The microwave circuit and housing as defined by claim 3 and further including an input connector and an output connector positioned in opposing end walls, and means connecting said connectors to said plurality of microwave circuit.
Claim 6
Dependent Claim
21 words
The microwave circuit and housing as defined by claim 1 wherein said plurality of slots and said pillar means are threaded.
Claim 7
Independent Claim
88 words
A method of mounting a microwave circuit including a carrier with tabs in a housing having a bottom surface and side walls comprising the steps of providing a plurality of slots in said side walls, said slots being parallel to said side walls and running from one edge to an opposing edge of each side wall, positioning said carrier on said bottom surface with said tabs extending into said slots, and inserting pillars into said slots thereby maintaining said carrier on said bottom surface and filling said slots.
Claim 8
Independent Claim
88 words
A method of mounting a microwave circuit including a carrier with tabs in a housing having a bottom surface and side walls comprising the steps of providing a plurality of slots in said side walls, said slots being parallel to said side walls and running from one edge to an opposing edge of each side wall, positioning said carrier on said bottom surface with said tabs extending into said slots, and inserting pillars into said slots thereby maintaining said carrier on said bottom surface and filling said slots.
Claim 9
Dependent Claim
24 words
The method as defined by claim 6 wherein said step of inserting pillars into said slots includes threadedly engaging said pillars in said slots.
