Unlimited Power Division Ratio of Microstrip Balanced-to-Unbalanced Gysel-Type Arbitrary Power Divider

  • Zihui Zhu,
  • Zhongbao Wang,
  • Ye Fu,
  • Shaojun Fang,
  • Hongmei Liu and
  • Zhi Ning Chen

A microstrip balanced-to-unbalanced (BTU) Gysel-type arbitrary power divider without the high-impedance transmission-line (TL) section is proposed to eliminate the power division ratio (PDR) limit of the conventional microstrip BTU power dividers. Th...
