Abstract
A power splitter that has a small package size and repeatable electrical characteristics. The power splitter includes a low temperature co-fired ceramic (LTTC) substrate with several layers. Electrical components such as resistors, capacitors and ground planes are integrated within the LTTC substrate. A binocular core transformer is attached to the upper surface of the LTTC substrate and is electrically connected to the resistors, capacitors and ground plane. The transformer provides impedance matching and dividing functions. The LTTC substrate has electrically conductive vias extending through the layers. The vias are used to connect the power splitter to terminals on outer surfaces of the substrate and to make electrical connections between the layers of the LTTC substrate. The power splitter circuit requires only one transformer.
