Abstract
A high frequency power divider circuit for distributing an input signal to two or more signal output ports, comprising: a rat race coupler, wherein the rat race coupler is configured to couple an input signal provided at an input port of the rat race coupler to a first output of the rat race coupler and to a second output of the rat race coupler; a first coupling structure coupled to the first output of the rat race coupler, to couple the first output of the rat race coupler with a first signal output port; and a second coupling structure coupled to the second output of the rat race coupler, to couple the second output of the rat race coupler with a second signal output port; wherein a characteristic impedance of a first transmission line portion between the input port and the first output of the rat race coupler deviates from a nominal ring impedance of the rat race coupler in a first direction, and wherein a characteristic impedance of a second transmission line portion between the input port and the second output of the rat race coupler deviates from the nominal ring impedance of the rat race coupler in a second direction, which is opposite to the first direction.
