Abstract
A reduced length filter including a housing having a female connector end and an opposed male connector end, and a circuit board positioned within the housing. The circuit board has first and second filter sections positioned on upper and lower surfaces thereof, and a ground plane positioned therebetween. The first filter section is in electrical communication with the second filter section. A first isolation shield is provided in electrical communication with the ground plane, and extends from the upper surface of the circuit board in a direction substantially perpendicular thereto and proximate one of first and second ends of the circuit board, and a second isolation shield is provided in electrical communication with the ground plane, and extends from the lower surface of the circuit board in a direction substantially perpendicular thereto and proximate the other one of the first and second ends of the circuit board.
