“…S ss11 and S ddAB are reflection coefficient of unbalanced port and isolation between balanced ports, respectively. For an ideal UTB PD with arbitrary power division, the requirements in terms of mixed-mode parameters are similar to the reported UTB PDs in [18,20]. The only differences are in terms of power division from unbalanced port to balanced ports.…”

“…BTU PDs for equal power division are reported in [13][14][15], and that for arbitrary power division is reported in [16]. UTB equal PDs are reported in [17][18][19][20]. In [17], UTB equal PD is designed using Mrachand balun, but no isolation element is present in the design.…”

Abstract-In this paper, Gysel type Unbalanced-to-Balanced (UTB) Power Divider (PD) with arbitrary power division is proposed. UTB PD is a five-port device, and a standard scattering matrix for a five-port PD with arbitrary power division is derived. Design equations are obtained analytically. Using design equations, a UTB PD is designed at 2 GHz for power division ratio of 1 : 2, and simulation is carried out using HFSS. A prototype is fabricated, and measurement is performed to verify the simulation results of PD. Measured results are in good agreement with the simulated ones. The proposed PD shows in-phase characteristic within ±5 • . Measurement results show that isolation between two output ports is greater than 20 dB. Greater than 20 dB common-mode suppression from input port to output balanced ports is achieved. Differential-mode power is divided in power division ratio of 1 : 2 from unbalanced port to balanced ports. Measured fractional bandwidth of the proposed PD is 21%.

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.
