Patent ID: 8068796

Claim:
A power divider comprising: a substrate comprising a first layer, a second layer and a third layer, the second layer formed between the first layer and the third layer; a signal reception terminal, formed in the first layer of the substrate, for receiving a signal to be transmitted; a first output terminal, formed in the first layer of the substrate, for outputting a first radio-frequency signal; an impedance matching terminal, formed in the third layer of the substrate, for coupling with an impedance; a second output terminal, formed in the third layer of the substrate, for outputting a second radio-frequency signal; a grounding plate, formed in the second layer of the substrate, surrounding a hole and forming a circular shape; a first block transmission line, formed at a position corresponding to the hole in the first layer of the substrate and coupled to the signal reception terminal and the first output terminal; and a second block transmission line, formed at a position corresponding to the hole in the third layer of the substrate and coupled to the impedance matching terminal and the second output terminal, and having a shape identical to a shape of the first block transmission line.
