“…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. Recently, new types of balanced‐to‐unbalanced (BTU) PDs are widely reported in the literature . The advantage of such PDs is that they can reject common‐mode noise and at the same time easily connected with the single‐ended devices.…”

This article proposes a Gysel type dual‐band balanced‐to‐unbalanced (BTU) power divider (PD) for equal power division. The proposed PD has out‐of‐phase (phase difference between two output signal is 180°) characteristic. Standard [S] matrix for the dual‐band PD is derived from mixed mode [S] matrix. Analysis is carried out to obtain design equations of the PD. The proposed PD is designed for a frequency ratio of 1.91. The two design frequencies are 2.2 and 4.2 GHz. A prototype is fabricated to validate theory and design equations. Measurement results show the dual‐band nature and out‐of‐phase characteristic of PD. Size of the fabricated prototype is 0.52λg × 0.29λg. The proposed PD configuration can also be used for high power application.

In this article, the filtering balanced‐to‐single‐ended power dividing networks are proposed. Except the fundamental functions of differential‐mode transmission, common‐mode suppression, and out‐of‐phase single‐ended output ports with isolation, the proposed designs show the advantages of wide controllable range of differential‐mode bandwidth, multiple transmission zeros (TZs), and wide bandwidth for high out‐of‐band suppression. The frequencies of TZs, bandwidth, isolation, and common‐mode suppression can be controlled by the parameters. For demonstration, three prototypes (Deigns I, II, and III) with two, four, or six TZs are implemented. The measured results show that design I (II and III) has an insertion loss of 0.38 dB (0.7 dB and 0.8 dB), an operating bandwidth of 12.5% (7.5% and 6.9%), and a bandwidth for 30‐dB out‐of‐band suppression of 0.06f0 (0.09f0 and 0.14f0). The isolation and common‐mode suppression inside the passbands of the three prototypes are all larger than 17 and 38 dB, respectively.

“…Balanced‐to‐unbalanced power dividers also have the function of common mode suppression, and they have more flexibility and freedom to connect with single‐ended or balanced circuits, which can be realized to design feeding network for the antenna array and the active power amplifies. In, the first balanced‐to‐unbalanced power divider using a shorted coupled lines and T‐shaped sections was proposed, but the bandwidth is only 25% and it not fit for wideband application. In addition, two balanced‐to‐unbalanced filtering power dividers based on branch lines and open stubs are realized, while their bandwidths were only 7.7 and 5% .…”

Two novel wideband balanced‐to‐unbalanced power dividers based on transmission lines and coupled lines are proposed in this article. Multifunction can be realized without cascading single devices with common mode suppression. The desired power divider configurations can be obtained using the even/odd‐mode characteristic impedance of the coupled lines and characteristic impedance of the transmission lines. A resistor in the middle of two single‐ended ports is used to realize isolation between output ports. Two prototypes of wideband balanced‐to‐unbalanced power dividers operating at 2.3 GHz with differential‐mode bandwidths of 79.6 and 134.1% are designed and fabricated. The theoretical and measured results are in good agreement and show good in‐band performances.
