Abstract
A printed balun satisfies performance requirements for operation at a desired operational frequency (e.g., ƒ=5.3 GHz) while minimizing space requirements on a circuit board. Segments of microstrip are connected at right angles that define fingers whose dimensions can be tailored for operation at a desired operational frequency while minimizing the corresponding space required on a circuit board. Minimal separation between the fingers avoids undesirable internal interference. Mounted at the edges of distinct fingers are the necessary ports for operation of the balun including a single-ended port, an isolation port, and two differential ports.
