Differential power divider/combiner with opposing spiral configurations

A differential Wilkinson power divider, comprising:

• an input shunt inductor between a positive input terminal and a negative input terminal;
• a first isolation inductor between a first positive output terminal and a second positive output terminal;
• and
• a second isolation inductor between a first negative output terminal and a second negative output terminal,
• wherein the first isolation inductor and the second isolation inductor have a first mutual inductance, the input shunt inductor and the first isolation inductor have a second mutual inductance, and a coefficient of coupling of the first mutual inductance has a higher magnitude than a coefficient of coupling of the second mutual inductance.
