A power splitter that has a small package size and low cross-talk noise. The power splitter includes a low temperature co-fired ceramic (LTTC) substrate with several layers. Electrical components such as transmission lines and resistors are integrated onto and within the LTCC substrate. The power splitter provides impedance matching and dividing functions. The LTCC substrate has counter rotating spiral shaped circuit lines and electrically conductive vias extending therethrough. The vias are used to connect the power splitter to an external printed circuit board. The vias are also used to make electrical connections between the layers of the LTCC substrate. The counter rotating circuit lines allow the power splitter to have a small package size and low cross-talk noise.
