Integral Broadcast Filter Switch

In a typical television or radio RF system, a switch is introduced between the transmitter output filter and transmission line, isolating the external part of the system (transmission line and antenna). The switch provides the capability to proof the transmitter into an RF load or troubleshoot if a problem exists in the transmission line or antenna. In this paper, a new filter technology that allows the integration of the switching into the filter itself will be discussed. There are potential benefits offered by this technique that can be expanded upon to contribute to simplified systems.
