I am going to design a series power divider. Example: http://www.waves.utoronto.ca/prof/gelefth/publications_files/Marco_Divider_MWCL.pdf [Broken] (The TL divider in Fig.1b ) But I don't know how to design the length of the transmission line and the characteristic impedance. Also , is there any different if there are only 3 output ports!? When I found the information about series power divider likes the TL divider in Fig.1b, the search engine showed many info. about Wikinson. Is there any information about series power divider but Wikinson?
