This paper describes a simple design of a broad-band four-way power divider with 45-degree phase differences between output ports. In the first stage of our work, we present a new broad-band 90-degree power divider. The phase error of the power divider here is less than one-tenth of the conventional 90-degree branch-line hybrid. Next, an experimental UHF-band four-way power divider using a broad-band 90-degree power divider and two broad-band 45-degree power dividers is presented. Over the frequency range from 0.86 to 1.06 GHz, the experimental four-way power divider exhibits power splits of -6.42±0.25 dB, return losses of greater than 15 dB, errors in the desired relative-phase difference between output ports of less than 1 degree, and isolation between output ports of greater than 15 dB. This divider is useful for realizing low distortion and high efficiency amplifiers without the need for an isolator.
