Abstract
MLC (multilayer ceramic) frequency selective circuit structures are disclosed. The MLC frequency selective circuit structures have a solenoid and toroid coil geometry in a multilayer electronic package which functions as a frequency selective tuned circuit in which both the number of turns and the aspect ratio of the solenoid coil are selected to adjust the tuned frequency. In some embodiments, a plurality of such coils can be connected together to provide a selected bandwidth about a tuned center frequency.
