Abstract
A filter comprises components arranged in a plurality of compartments which are magnetically shielded from each other. Each compartment includes components for filtering two frequencies wherein these frequencies are separated by an amount such that inductive coupling is substantially prevented. The compartments are combined to increase the attenuation, and any number of compartments may be utilized to filter the desired number of frequencies.
Claims8
A filter comprising at least two compartments including first and second compartments, means for magnetically isolating said first compartment from said second compartment, first filter means for removing a first frequency range and having cooperating components in each of said first and second compartments, and second filter means for removing a second frequency range and having cooperating components in said first and second compartments, said cooperating components of each of said first and second filter means comprising discrete inductive and capacitive elements, wherein said first frequency range differs from said second frequency range by an amount such that magnetic coupling between said components of said first and second filter means in each of said first and second compartments is substantially prevented.
