“…These designs also require an increase in length. Other works [21], [22] focus on the isolation network design for isolation bandwidth improvement. Length increment is avoided by modifying only the isolation network.…”

Cataloged from PDF version of article.We propose an isolation network to simultaneously\ud improve the input return loss, output return loss and isolation of\ud the Wilkinson power divider in a wide bandwidth. The required\ud even mode and odd mode reflection coefficients of the isolation network\ud are calculated. Constructed even and odd mode circuits are\ud combined to give the desired isolation network. Analytical expressions\ud for the optimal component values for a single-section divider\ud are given. Compared with the single-section Wilkinson divider, the\ud final design can triple the bandwidth for an input-output return\ud loss and isolation of greater than 25 dB. Broadband characteristic\ud is achieved without increasing the number of sections hence extra\ud length and insertion loss are avoided. Wide operation bandwidth\ud of the new divider is verified by experimental results. The proposed\ud method can be applied to a two-section divider, also broadening its\ud bandwidth

“…The calculated performance using (8) in the model (1)- (6) is depicted in Fig. 3 b. The results indicate that the isolation is better than 15 dB and the differential phase is 180°±10° across an octave bandwidth.…”

“…Since the most used power dividers (Wilkinson power divider/combiner [1], [7], [8]) are inherently inphase devices, several methods were proposed to make it an out-of-phase divider/combiner. Some of those methods include using 180° phase shifters [9], or microstrip to slotline transitions [10].…”

“…Recently there is great interest in wideband highperformance power dividers. Several techniques devised to improve the bandwidth of the Wilkinson power divider are multi-section [2], step impedance matching network [3], openor short-ended stubs [4], port extension [5] and additional isolation network [6]. These ways could effectively improve the input/output return-loss, or isolation bandwidth.…”

This paper proposes the design of two-way Nsection equal split Wilkinson power dividers. 1-to 4-section Wilkinson power dividers using strip-lines are designed and optimized to analyze the trends of VSWR (Voltage Standing Wave Ratio), isolations and losses. On the rigorous premise of VSWR≤1.13 and isolation≤-20dB, the bandwidths are respectively 25%, 52%, 93%, and 120%. Especially, according to the comparison, with the increase of the number of isolation resistors, the resistor loss contributes more to the total loss than the dielectric loss and the conductor loss. Based on the analysis, numbers of sections and resistors are supposed to be determined appropriately to satisfy all requirements.
