Abstract
A split tuning filter is disclosed in which at least two separate electrically interconnected filter sections mounted on a common circuit board are magnetically isolated through an isolation area defined by a pair of spaced isolation shields. A conductor interconnecting the two filter sections passes through the isolation area and has an external terminal connected thereto which allows each of the two filter sections to be independently tuned, with the isolation area minimizing the tuning impact of one filter section on the other. To further increase magnetic isolation, respective resonating capacitors provided in the filter sections have grounded plates perpendicularly interposed in the line of sight between primary tuning coils which are also respectively provided in the filter sections, with the grounded plates facing toward the isolation shields.
