| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Power dividers are used to divide the input power into a number of smaller amounts of power for exciting the radiating elements in an array antenna. They are also used in balanced power amplifiers both as power dividers and power combiners. We devise a tunable branch line coupler that power distribution ratio, and study the improvement of the design accuracy. Circuit of the present study, that the lateral circuit of the traditional branch line coupler is replaced by the M-type circuit transmission line, becomes possible to arbitrarily set the power distribution ratio by variable capacitors. | |
