For baluns embedded in an antenna, even a single coupled line behaves as a balun, because c-mode signals are suppressed in favor of its high characteristic impedance. A broad band balun, of which band is between 0.6 and 8.0 GHz, is reported with a broadside coupled line. The objective of this paper is to design a broadband balun operating in higher frequencies. For the purpose, structures for via-pads to shift the differential ports on the identical layer were examined, as well as the line width was reduced. The pad’s differential characteristic impedance was simulated and optimized to be 50Ω by overlapping the via-pads. Baluns consisting of a 4-mm-long coupled line and the via pads, were designed and fabricated. Measured insertion loss was less than 2 dB between 1.0 GHz and 12.0 GHz. |
