摘要：
A system includes an input node, a frequency translatable impedance (FTI) filter, and a radio frequency (RF) downconverter module. The input receives an input signal having first and second components. The FTI filter filters the second components. The RF downconverter module receives the first components and downconverts the first components. Both the FTI filter and the RF downconverter module communicate with the input node.
