An advanced electronics package for integrating electronic components of an electronic circuit, such as RF circuits. An important aspect of the invention relates to the simplicity in forming and integrating the electronic components in the package relative to known electronics packages. In one embodiment of the invention, various ceramic preforms are utilized which may be cast with temperature durable electronic components or formed as interconnect channels or feedthroughs. The preforms, in turn, are adapted to be cast into a composite housing, for example, an aluminum silicon carbide (AlSiC) housing. The component preforms may include resistors, capacitors, and inductors. In addition, RF pins as well as DC pads may be cast in the housing. The electronic components are electrically coupled to an interconnect channel or feedthrough. Interconnections by way of the interconnect channels or feedthroughs within the package may be made by way of metal infusion of a metal, such as aluminum, into the ceramic of the interconnect channels. In an alternate embodiment of the invention, a polymer based integrated package, formed from a polymer, is molded around a cast base which acts as a heat sink. Interconnection between the various electronic components is made by either molding interconnect metal tracings in the polymer housing or by way of interconnection vias which are filled with polymer based conductive paste or immersion plating. In both embodiments, interconnections between electronic components forming the electronic circuit are made without the use of glass feedthroughs which greatly simplifies the cost and complexity of the package. <IMAGE> |
