摘要： A power divider includes an input capacitor, and first and second transmission lines (TLs). The first TL includes an input portion (IP), a transmission portion (TP) and an output portion (OP). The second TL includes a TP and an OP. The IP is for receiving an input signal, and is connected to the TPs of the first and second TLs. For each of the first and second TLs, the TP has a length that is one-twelfth of a target wavelength, and is connected to the OP. The OPs of the first and second TLs are for cooperatively outputting a pair of output signals which are in-phase and each of which has a frequency equal to that of the input signal. The input capacitor is connected between ground and the IP.
