Abstract: This paper covers design of compact BALUN transformer using Klopfenstein transformer. The verification of BALUN is done through three different approaches. First approach is to connect 100 Ω SMD resistor and then using two different dipole antennas covering Bluetooth and WiMax applications. All the measurements are satisfactory and confirms the successful design of compact Klopfenstein BALUN transformer.

Keywords: Coplanar stripline, Bluetooth, WiMAX, BALUN, taper transformer, Klopfenstein transformer.
