The losses and parasitics associated with MMIC technology prevent the realization of high-Q passive components, a necessity for highly-selective low-loss filters. For applications such as communications and radar, passive filters are preferred over active filters due to the latter's issues with linearity and stability. This paper investigates the value of using highly-selective but lossy filters implemented using low-Q components. It is shown that equivalent system performance can be achieved with such a filter using a modified receiver architecture. A simplified lossy design technique using resistive-compensating networks is also presented.
