A broadband asymmetric tapered-line power divider with several strip resistors

A novel asymmetric tapered-line power divider is presented. It has several strip resistors which are formed like a ladder between the tapered-line conductors to achieve a good output isolation. The equivalent circuits are derived with the even/oddmode analysis. The fabricated asymmetric power divider with 1:2 power dividing ratio shows broadband performances in return loss and isolation which are greater than 20 dB over a 3:l bandwidth in the C-K bands.
