Filed:

Nov 7, 2003

Appl. No.:

10/704402

Inventors:

Roger L. Valentine - Santa Rosa CA
Anthony R. Blume - Santa Rosa CA
Michael J. Neumann - Milwaukee WI
Adam E. Robertson - Rohnert Park CA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

H05K 900

US Classification:

174 35GC, 257698, 257728, 257704

Abstract:

A contiguous gasket provides an electromagnetic and environmental seal between the base and lid of a microcircuit housing. The base has a flat surface that allows easy access of tools for assembling electronic components. Channels are cut into a corresponding flat portion of the lid to accommodate the electronic components mounted on the base. High-frequency feedthroughs are brought through sidewall connector features of the base that rise above the assembly surface. Feedthroughs are optionally brought through the flat portion of the base as well. When the microcircuit housing is assembled, the lid compresses the gasket against the base to form an electromagnetic and environmental seal.

Abstract:

An integrated contact is disposed on the end of a conical coil form. Fine magnet wire is soldered to the integrated contact and wound around the coil form to fabricate a high-frequency inductor for use in high-frequency chokes and other high-frequency devices. In one embodiment, the integrated contact is plated on the tip of a polyiron coil form and less than one turn of wire is wrapped around the plated portion of the polyiron coil form. The integrated contact has reduced contact area, reducing capacitive coupling and improving high-frequency electrical performance.
