RF PACKAGE
First Claim
1. An RF package comprising:
- a substrate mountable on a base plate;
a non-conductive cover overlying the substrate and including;
a recess configured to receive the substrate, the recess forming a stress distribution surface area to engage and press outer edge portions of opposite sides of the substrate against the base plate;
one or more tapered lower surfaces extending from the recess toward outer edge portions of the cover; and
one or more stepped source leads extending from at least one of a pair of opposite sides of an upper surface of the substrate to the one or more tapered lower surfaces of the cover.

Abstract
An RF package includes a substrate mountable on a base plate, a non-conductive cover overlying the substrate, and quasi-serpentine stepped source leads attached to an upper surface of the substrate and extending from at least one of a pair of opposite sides of the upper surface of the substrate to tapered lower surfaces of the cover. The cover includes a recess to receive the substrate. The recess includes stress distribution surface areas to engage and press outer edge portions of opposite sides of the substrate against a base plate or heat sink. The tapered lower surfaces of the cover engage with and press against the stepped source leads when securing the RF package to the base plate or heat sink using one or more fasteners or bolts. The cover includes structural features to improve preferential deformation when a mounting force is applied.
