Baluns

Coupled line balun

Balun is a transformer used to connect an unbalanced source line to a balanced load or vise-versa. This structure provides a matching transition between unbalanced to balanced transmission lines with a 180 degree phase difference and an equal potential at the output port. Baluns are key components in balanced circuit topologies such as balanced mixers, push-pull amplifiers, balanced frequency multiplier, phase shifters, balanced modulators, dipole feeds and other wide range of applications.
