1. A filter circuit assembly comprising:

  • a printed circuit board having first and second opposed major surfaces and first and second opposing sides, the opposed major surfaces being substantially parallel to a single plane and being bisected by a longitudinal axis, the first and second opposing sides being substantially parallel to the longitudinal axis;

    an input terminal connected to the printed circuit board, the input terminal having an axis extending substantially parallel to the longitudinal axis;

    an output terminal connected to the printed circuit board, the output terminal having an axis extending substantially parallel to the longitudinal axis;

    a signal path disposed on the printed circuit board, the signal path extending from the input terminal toward the output terminal;

    a plurality of resonator elements being fabricated upon at least one of the major surfaces, the resonator elements arranged in series along the signal path and defining a footprint being less than 540 square millimeters; and

    wherein the filter passes a first range of frequencies in a provider bandwidth and attenuates a second range of frequencies in a personal data network bandwidth.
