ABSTRACT:
A multi-stage power divider particularly adapted for use in microwave circuits consists of a plurality of transmission lines and resistances uniquely arranged to achieve a wide range of power division and to give the power divider broad bandwidth and high isolation. The power divider is particularly easy to design and manufacture in stripline and microstrip constructions. The divider provides coupling in the range of 3 dB to 20 dB with high isolation and in a single-layer construction.
