RF LC Balun Calculator Formula or Equation

The figure below illustrates a typical LC bridge configuration, often referred to as a lattice-type balun.

This design uses two inductors and two capacitors. These components create approximately +/- 90 degrees of phase shift between the input and output signals.

The following equation or formula is used in the RF LC Balun Calculator:
