Implementation of a broadband Ruthroff-type transmission line transformer balun with a 1: 2 step-up impedance transformation ratio is presented in this letter. The proposed Transmission Line Transformer (TLT) balun was investigated with broadside-coupled lines using three stacked microstrip lines. The proposed balun was formed by cascading one section of modified Ruthroff-type 2: 1 unbalanced-to-unbalanced TLT with one section of Ruthroff-type 1: 4 TLT balun in series. The achieved fractional bandwidth of the balun is 192.17% over the frequency range from 1.2 to 6.6 GHz, which covers the IEEE 802.11 a/b/g WLAN, WiMAX applications. The measured amplitude and phase imbalances are less than 1 dB and less than 4.51?, respectively at this frequency range. [ABSTRACT FROM AUTHOR] |
