A New Dual Band Balanced-to-Balanced Power Divider

Abstract

Abstract-In this paper, a new dual band balanced-to-balanced power divider is proposed. By using the dual frequency 90 • phase shifter based T model, the proposed balanced-to-balanced power divider can be deduced. By using the method in our previous work, the dual band balanced-to-balanced power divider could be designed with 1 : 1 power division. This balanced-to-balanced power divider is implemented on microstrip structure. Comparing the results calculated in analytical method with that simulated by the full-wave electromagnetic simulator, and that measured by the network analyzer, the final results show that they have a good mixed mode performance. The pass band 1 is from 2.395 GHz to 2.550 GHz, and the pass band 2 is from 5.245 GHz to 5.30 GHz. The maximum isolations for pass band 1 and pass band 2 are 17.8 dB and 17.6 dB, respectively.

A design of single‐ended to differential‐ended power divider for X band application

“…Although an air bridge and multilayer crossovers have wide bandwidths with good isolation, these crossovers significantly increase the fabrication complexity, size, and cost. To overcome these drawbacks, various planar crossovers have been proposed [4][5][6][7][8][9][10][11]. Window-shaped and multisection crossovers were proposed [4,5].…”

Dual‐band balanced‐to‐unbalanced out‐of‐phase equal power divider

“…A dual‐band balanced PD is reported in ref. . This dual‐band PD is similar to its single band counterpart, only the difference is all 90° and 180° transmission lines are replaced by dual‐band 90° and 180° phase shifter.…”

A Balanced-to-Single-Ended Wilkinson Power Divider

“…By using half-mode substrate integrated waveguide (SIW) structure, a balanced symmetric Gysel power divider is designed [5]. Also, balanced Gysel power divider with arbitrary power division ratio [6] and dual-band balanced Wilkinson power divider [7] are designed.…”

“…The most important advantage is the ability of anti common-mode interference. As power divider is an important microwave/millimeter wave passive device, scholars have made a deep research on balanced power dividers [1][2][3][4][5][6][7].In [1], a wide band miniature balanced power divider is designed with the coupled lines.…”
