A design of a wideband in-phase power divider/combiner has been presented in Abbosh and Henin (2013). The authors based their design on the traditional Gysel power divider structure and modifled the isolation resistors and the line impedances to obtain the proposed divider. As a matter of fact, it can be shown that the suggested modiflcations of Gysel power divider can be derived as a special case of the more generalised studies in the literature. This communication shows how the results of Abbosh and Henin can be reproduced in a more generalised form from the previous studies of the modifled Gysel power divider structure. The close relation between the proposed divider and the classical ring coupler is also manifested.
