Abstract
Apparatus and arrangements for reducing crossover coupling of two or more RF signals are described. In one case, a crossover structure is described where RF signals are routed through coplanar waveguides having a specific characteristic impedance and crossing at a central point of the crossover structure by way of a bridge. Further described is a multi-port rotary RF switch fitted with the crossover structure which allows substantially balanced electrical performance across all the operational states of the rotary RF switch at RF signal frequencies up to 50 GHz and beyond. A controller unit coupled to the RF switch can support a control interface to configure the rotary switch according to all possible distinct states of the rotary switch, or a subset thereof.
