Abstract
In this paper, a double-sided planar balun using Microstrip-to-CPW coupled structure is fabricated and measured. The measured amplitude and phase imbalance are, respectively, less than 0.2 dB and 2.1$^{\circ}$ in a wide frequency range from 2.44 GHz to 4.33 GHz. It is expected that the proposed balun can improved the performance of balanced mixer, amplifier and feeding network of antennas. Also, it can be used in many microwave multilayer structures due to its structural characteristics.
