Abstract:
An electronic signal filter comprising:a cylindrical housing adapted to be electrically grounded and having a first end, an opposed second end and an inner peripheral surface defining an interior compartment; a single circuit board positioned within said interior compartment of said cylindrical housing, said single circuit board having a first surface, a second surface, a first filter section and a second filter section adjacent said first filter section, said circuit board substantially dividing said interior compartment into a first compartment defined by said first surface of said circuit board and a first portion of said inner peripheral surface of said cylindrical housing, and a second compartment defined by said second surface of said circuit board and a second portion of said inner peripheral surface of said cylindrical housing; a first shield member extending from said first surface of said circuit board toward said first inner peripheral surface of said cylindrical housing; and a second shield member radially opposing said first shield member and extending from said second surface of said single circuit board toward said second inner peripheral surface of said cylindrical housing, said second shield member being electrically connected to said first shield member, and said second shield member being a discrete component from said first shield member; wherein at least one of said first shield member and said second shield member has a portion that extends through said circuit board beyond said second surface thereof or said first surface thereof, respectively.
