Abstract
An apparatus comprises a radio frequency filter and a dielectric material configured to alter the frequency response of the RF filter, wherein said dielectric material is located in proximity to said RF filter. The apparatus may be useful in a satellite antenna system wherein the RF filter is configured to have an initial frequency response. The dielectric material may be configured to shift the frequency response of the RF filter from the initial frequency response to a shifted frequency response. The dielectric material may be a polyimide tape. A method is also provided for reworking a non-compliant PWB, wherein the PWB is non-compliant with a standard frequency response to a given RF input signal, and wherein the PWB comprises an RF filter. The method comprises the step of adjusting the frequency response of the RF filter by adding a piece of polyimide tape in proximity to the RF filter.
