Example of a mixed-signal Global Positioning System (GPS) receiver using MCM-L packaging

Under an Advanced Research Projects Agency program (NRaD contract N66001-89-C-0104), a fully functional Global Positioning System (GPS) receiver using Laminated Multichip Modules (MCM-L's) was developed. Although many facets of GPS are of interest, this paper will use this particular module design as an example of a more generic mixed-signal (i.e., containing both analog and digital electronic elements) system, concentrating on the design, assembly, and test aspects related to typical mixed-signal MCM problems. Topics include system requirements, design constraints, substrate selection and description, design approach, assembly and test.<
