摘要： An efficient way to fabricate the channels and cavities in a LIMMS device is to form them as matching upper and lower portions each created as a patterned layer of thick film dielectric material deposited on a respective upper or lower substrate. The two portions are adhered together by a patterned layer of adhesive, and hermetically sealed around an outer perimeter. The heater resistors are mounted atop the lower layer, thus suspending them away from that substrate and exposing more of their surface area. Vias can be used to route the conductors for the heaters and the switched signal contacts through the lower substrate to cooperate with surface mount techniques using solder balls on an array of contact pads. These vias can be made hermetic by their placement within the patterned layers of dielectric material and by covering their exposed ends with pads of hermetic metal. Suitable thick film dielectric materials that may be deposited as a paste and subsequently cured include the KQ 150 and KQ 115 thick film dielectrics from Heracus and the 4141A/D thick film compositions from DuPont.
摘要翻译：在LIMMS装置中制造通道和空腔的有效方法是将它们形成为匹配上部和下部，每个上部和下部被形成为沉积在相应的上部或下部基底上的厚膜介电材料的图案化层。两个部分通过图案化的粘合剂层粘合在一起，并围绕外周密封。加热电阻器安装在下层的顶部，从而将它们悬挂在远离基板并暴露出更多的表面积。通孔可用于将加热器的导体和切换的信号触点通过下基板布线，以使用在接触焊盘阵列上的焊球的表面贴装技术配合。这些通孔可以通过它们放置在图案化的电介质材料层内并通过用气密金属垫覆盖其暴露的末端而形成为气密的。可以作为糊料沉积并随后固化的合适的厚膜电介质材料包括来自Heraeus的KQ 150和KQ 115厚膜电介质和来自DuPont的4141A / D厚膜组合物。

In particular, the module comprises a substrate; a conductive ground plane disposed above the substrate; a first dielectric layer printed on top of the ground plane; a microstrip disposed on top of the first dielectric; a second dielectric layer printed on top of the microstrip; a top ground plane disposed on top of the second dielectric; and a shield, electrically coupled to the top ground plane.

摘要： A solution to the problem of connecting a merchant straight through coaxial RF connector to an quasi-coaxial transmission line formed on the substrate of a hybrid is to, if necessary, gradually increase the height of the center conductor of the quasi-coaxial transmission line by increasing the thickness of underlying deposited dielectric until the center conductor of the transmission line matches the position of the center conductor of the connector, which two may then be joined with solder or conductive adhesive. One style of coaxial RF connector of interest has four prongs disposed in a rectangle around the center conductor on the permanent and non-threaded side. Two of the prongs define a long side of a rectangle and may be soldered or otherwise attached to the substrate with conductive adhesive, and the two prongs that define the long side closest to the center conductor can support a small cover that physically bridges and electrically shields the gap between the connector and the end of the quasi-coaxial transmission line. The cover provides complete shielding and assists in minimizing the discontinuity in characteristic impedance caused by the transition between the connector and the quasi-coaxial transmission line.

摘要： Quasi-coaxial transmission lines to be “crossed” (over) are fabricated on a substrate. There are two cases: a true ground plane of metal will cover the substrate, or, each quasi-coaxial transmission line will have its own separate meandering bottom-half ground shield. In either case, when the crossed quasi-coaxial transmission lines are complete they will have top-half ground shields connected to metal against the substrate that is ground. If there is no ground plane the “crossing” quasi-coaxial transmission line that is to cross over must now have its bottom-half ground shield applied. It can overlay any top-half ground shield for any crossed quasi-coaxial transmission line that is in its path. If there is a ground plane, then that step is not necessary. Now a bottom-half layer of KQ dielectric material is applied along the path of the crossing quasi-coaxial transmission line. To this layer of KQ dielectric material is applied a layer of metal that becomes the center conductor. The crossing quasi-coaxial transmission line is finished by printing a top-half layer of KQ dielectric, covered by a layer of metal that is the top-half of ground shield. The edges of this top-half ground shield touch either the ground plane or the outer portion of the bottom-half ground shield.

摘要： A hybrid circuit having a quasi-coaxial fully shielded conductor, and incorporating a ground plane on the component side of a substrate, can bypass and/or filter a signal using integrated thick film components and without through holes or vias. A thin pad of suitable dielectric material may be printed onto the ground plane and then have a layer of metal deposited on its top surface, forming a bypass capacitor. The bypass capacitor can be located very near where it is needed, and only a very short conductor is required to connect the metallic top of the bypass capacitor to the location to be bypassed. The short connecting conductor does not go from one side of the substrate to the other, and the thickness and low dielectric constant of the substrate do not compromise the value of the bypass capacitor. Thick film resistors can be included to form filters, and surface mount resistors and capacitors can be used also.
