Abstract

A system includes an RF input coupled to a plurality of channel filters through an inductive manifold. Each of the channel filters is configured as a series resonator and has a frequency of greater than about 1 GHz. The frequency of the channel filters decreases as their distance from the RF input increases. Components of each of the channel filters, which may include a series inductor, series capacitor, and shunt capacitor, are configured using high-Q transmission lines. A tunable notch filter, such as an absorptive tunable band-stop filter, may be included within the channel filters. The system may be used for protection of wideband receivers.
