Abstract
Apparatus for mounting a diode in a microwave circuit for making electrical contact between the circuit and ground and for dissipation of heat between the diode and a heat sink. The diode, supported on a thermally and electrically conductive member, is resiliently pressed in electrical contact with the microwave circuit. A tapered collar on the member is elastically deformably wedged into a tapered aperture formed in a heat sink. The wedged collar tightens firmly around the member establishing good thermal and electrical conduction from the diode to the heat sink and ground. Disassembly is facilitated because of the elastically deformed collar.
Claims12
An apparatus for mounting a diode in a microwave circuit, said microwave circuit including a conductor affixed to a substrate, said substrate having an aperture for receiving said diode to make contact with the surface portion of said conductor in register with said aperture, comprising:
- means for resiliently pressing said diode into electrical contact with said conductor through said aperture;
- and
- support means for fixedly supporting said resilient means, said support means having an elastically deformable portion to hold said diode substantially rigidly in contact with said conductor whereby said support means is prevented from jamming in position.
An apparatus for mounting a high-power diode in a microwave circuit comprising:
- a. a mounting block for heat sinking and electrical ground;
- b. a microwave circuit affixed to a substrate, said substrate being mounted on said block;
- c. a tapered aperture extending through said block converging to said substrate;
- d. an aperture in said substrate in register with said tapered aperture for receiving said diode;
- e. a thermally and electrically conductive member for supporting said diode in said aperture;
- f. a tapered collar on said member shaped to mate substantially with said tapered aperture;
- and
- g. means for wedging said collar against the tappered surface of said aperture and resiliently pressing one terminal of said diode in electrical contact with said microwave circuit, said collar establishing a good thermal path from said diode to said block and electrical conduction from the other terminal of said diode to said block.
