High power shunt switch with high isolation and ease of assembly
First Claim
1. A high power shunt switch comprising:
- a leadframe including paddle for supporting a shunt element, and a plurality of bond pads located around a periphery of the paddle, wherein at least a first subset of the bond pads are aligned in a substantially straight-line configuration;
a shunt element fixedly attached to the paddle;
a wire bond for connecting the shunt element to a top surface of one the at least first subset of bond pads;
an encapsulant disposed on the paddle, the shunt element, the plurality of bond pads, and the wire bond, thereby forming a package structure; and
a transmission line attached to bottom surfaces of each of the at least first subset of bond pads, thereby forming an electrical connection between the shunt element and the transmission line, wherein the transmission line and package structure are fixedly attached to a suitable substrate.

Abstract
A high power shunt switch comprises a leadframe including a paddle for supporting a shunt element, and a plurality of bond pads located around a periphery of the paddle, wherein at least a first subset of the bond pads are aligned in a substantially straight-line configuration. A shunt element is fixedly attached to the paddle and wire bonded to a top surface of one the bond pads. An encapsulant is disposed on the paddle, the shunt element, the plurality of bond pads, and the wire bond, thereby forming an encapsulated package structure. The package structure is positioned and attached to a transmission line such that the bottom surfaces of each of the at least first subset of bond pads are in simultaneous contact with the transmission line. The package structure and the transmission line are fixedly attached to a suitable substrate.
