Abstract
A receiver or transmitter designed for a broad range of frequencies requires a pre-select filter for incoming signals or a post-select filter for outgoing signals to minimize spurious signal responses. In conventional receivers, several discrete RF filters are used and a switched filter bank is created utilizing a large amount of space. A filter bank comprising a plurality of stacked shielded filters would enable different filter technologies and topologies to be used together, as other passive and active circuits may be combined into the one surface mountable component in order to save on PCB space.
