- A simple microstrip wideband balun with low insertion loss for high-power operation is proposed. The balun is fabricated using one Wilkinson divider and two 3-dB quadrature couplers. A Wilkinson divider with a three-section structure is used for power splitting. A 180째 phase difference is obtained by using two quadrature couplers with a twisted-pair coaxial cable. Experimental measurements show that the fabricated balun has an amplitude imbalance of 짹0.5 dB and a phase imbalance of 짹3.4째 with an insertion loss of 짹1.3 dB over frequencies ranging from 700 to 2500 MHz. © 2005 Wiley Periodicals, Inc.
