ABSTRACT:
A two piece zinc die-cast housing and cover assembly includes an internal center wall structure which divides the included space into two electromagnetically isolated cavities. A VCO circuit sub-assembly and a PLL circuit sub-assembly are each removably affixed to respective opposite sides of the center wall while each is electrically interconnected to the other directly through at least one aperture provided in the center wall. A one piece molded plastic header is removably affixed to the assembly so as to close the remaining side of the electromagnetically isolated cavity and includes apertures through which electrical leads extend from the circuit sub-assemblies for self-aligning connection to sockets or other external electrical connectors. An additional internal metallic shield directly affixed to the VCO sub-assembly as well as other features cooperate to provide an overall improved frequency synthesizer module of this general type.
