US 12,476,342 B2 · Power divider supporting different numbers of outputs

Abstract

A device configured to support different numbers of outputs. The device includes an input port configured to receive an input signal. The device also includes a first transmission line characterized by a first characteristic impedance and coupled to a first output port. A switch is configured to either connect or disconnect the first transmission line to the input port. The device also includes a second transmission line characterized by a second characteristic impedance and coupled between the input port and a second output port. A controller is configured to activate the first switch to set a two-output mode or to deactivate the first switch to set a one-output mode. The second characteristic impedance is configured to be the same as the first characteristic impedance at the two-output mode or configured to be reduced to 1/√{square root over (2)} of the first characteristic impedance at the one-output mode.
