Abstract:
1. A switchable combiner for minimizing route-based disparity in insertion loss, comprising: first and second input ports for transmitting inputted signals; first and second lines connected to the first and second input ports, respectively, for transmitting the inputted signals; a common contact point for combining the signals transmitted from the first and second lines; first and second switching means, respectively, for switching the common contact point with the first and second lines based on a number of routes; a third line connected between the common contact point and an output port for receiving a signal outputted from the common contact point and transmitting the signal to the output port; the output port connected to the third line for outputting the signal transmitted from the third line; a third switching means for switching the third line and a short stub; an open stub connected to the third line for setting up matching condition with respect to a maximum route number; and the short stub for performing matching with respect to route numbers other than the maximum route number, wherein an end of the short stub is connected to a ground, and the other end of the short stub is connected to the third line.
