Abstract
A filter package for communications equipment includes two or more filters in die form, each having a different frequency response. A first switch and a second switch are operatively connected to the filters and are configured to select a desired filter for operation in a signal stage of the equipment. The filters are aligned and stacked one over the other in the form of a package having an input terminal that is tied to a common terminal of the first switch, and an output terminal tied to a common terminal of the second switch. When the input and the output terminals of the filter package are connected to corresponding terminals of an intermediate frequency (IF) stage in a communications transceiver, the package can support both narrowband and wideband waveforms defined by the Joint Tactical Radio System (JTRS).
