Electrical filter with multiple filter sections.

摘要

An electrical filter (40) having first (41) and second (42) filter sections with respective sets of electrical filter components. These sets of electrical filter components include primary tuning coils (53,54) which are arranged parallel to a reference axis. An electrical isolation shield (45) is disposed on a reference plane between the first and second filter sections for electrically isolating the sections from one another, the reference plane being orthogonal to the reference axis. The unique configuration of the filter sections allows for the filter sections to be independently tuned while being physically and electrically isolated from one another. The filter sections are then coupled to one another both physically and electrically subsequent to the tuning operation.
