Abstract:
1. A power splitter comprising: a) a substrate having a top layer, a bottom layer, and a plurality of inner layers; b) a first resistor formed on the top layer, the first resistor having a first and second end; c) a second resistor formed on the top layer, the second resistor having a third and fourth end, the second end of the first resistor connected to the fourth end of the second resistor; d) a third resistor formed on the top layer, the third resistor having a fifth and sixth end, the second end of the first resistor connected to the fifth end of the third resistor; e) a capacitor formed between the inner layers, the capacitor having a seventh end and an eighth end; f) a plurality of terminals located on the top and bottom layers; g) a plurality of vias extending through the substrate, the vias electrically connecting the resistors, the capacitor and the terminals; h) a first transformer attached to the top layer and connected to a first terminal, the first terminal forming an input port, the seventh end of the capacitor connected to the first transformer, the eighth end of the capacitor connected to a ground terminal; i) a second transformer attached to the top layer and connected to a second terminal, the second terminal forming a first output port, the first end of the first resistor connected to the second terminal; j) a third transformer attached to the top layer and connected to a third terminal, the third terminal forming a second output port, the third end of the second resistor connected to the third terminal; and k) a fourth transformer attached to the top layer and connected to a fourth terminal, the fourth terminal forming a third output port, the sixth end of the third resistor connected to the fourth terminal, such that an electrical signal applied to the input port is split between the first, second and third output ports.
