Latest Patents
John M Dunn holds a patent for a high isolation RF switch. This invention features a three-switch configuration that allows for the selection of one of two RF signals to be launched into a slabline transmission line structure. The design includes a pair of input switches connected to corresponding input ports and a transition switch linked to an output port via the slabline transmission line. The input switches facilitate the selection of one input port for coupling to the transition switch, which then connects the chosen input port to the output port. To enhance isolation between the input ports, a grounded conductor is positioned within a cavity of the housing that contains the RF switch. Additional isolation is achieved by grounding the non-selected RF signal, either through the transition switch or the non-selected input port.
