“…If we still set the electrical length of each transmission line as a quarter‐guided wavelength at the centre frequency, the power dividing ratio is defined as

P_{1} : P_{2} : P_{3} = k_{1}^{2} : k_{2}^{2} : k_{3}^{2}

Then, the impedance of distributing networks is

Z_{0 n} = \sqrt{(k_{1}^{2} + k_{2}^{2} + k_{3}^{2}) R_{x 0} R_{x n} / k_{n}^{2}}, n = 1, 2, 3

where R x 0 and R xn are the characteristic impedances of the common port and distributing ports, respectively. Following the derivation process in [31], the relationships between voltages and currents in the distributing network are

({, \begin{aligned} U_{0} = - j \frac{U_{1} R_{x 0}}{Z_{01}} \\ I_{1 c} = I_{1 c 2} + I_{1 c 3} = U_{1} ()(, \frac{1}{R_{x 1}} - \frac{R_{x 0}}{Z_{01}^{2}}) \\ I_{2 c} = I_{2 c 1} - I_{2 c 3} = \frac{U_{1} R_{x 0}}{Z_{01} Z_{02}} \\ I_{3 c} = I_{3 c 1} + I_{3 c 2} = \frac{U_{1} R_{x 0}}{Z_{01} Z_{03}} \end{aligned}),

“…Generally, the port impedances of common port R x0 and distributing ports R xn are unified to Z 0 for circuit simplification and realisation convenience. Thus, (9) can be expressed as

({, \begin{aligned} Z_{n m} = p_{m n} Z_{m n}, R_{n m} = q_{m n} R_{m n} \\ Z_{0 m} = \frac{Z_{0}}{K_{m}} \sqrt{false(K_{1}^{2} + K_{2}^{2} + K_{3}^{2} false)} \\ Z_{m n m} = \sqrt{\frac{(K_{1}^{2} + K_{2}^{2} + K_{3}^{2}) Z_{0}}{K_{n}^{2}} ∙ \frac{q_{m n} R_{m n}}{p_{m n}^{2} + q_{m n}}} \\ Z_{m n n} = \sqrt{\frac{(K_{1}^{2} + K_{2}^{2} + K_{3}^{2}) Z_{0}}{K_{m}^{2}} ∙ \frac{q_{m n} R_{m n} p_{m n}^{2}}{p_{m n}^{2} + q_{m n}}} \\ m = 1, 2, 3 \\ n = 1, 2, 3, m < n \end{aligned})

In (10), R mn , p mn , q mn , Z mn and Z 0 can be arbitrarily positive values, which may affect the frequency bandwidth, as discussed in [31]. In this paper, to investigate the effect of the operating frequency bandwidth, the model of the three‐way Gysel power divider is built and shown in Fig.…”

“…Afterwards, a back‐to‐back microstrip structure was used to realise an N‐ way Gysel combiner in [30]. Based on the existing designs, we proposed an N ‐way Gysel power divider on the arbitrary terminated impedance with closed‐form equations of arbitrary power dividing ratio, which were derived by using the node voltage and current method in [31].…”

“…The traditional N ‐way Gysel power dividers presented in 1975 [28] and in [29–31] have identical structures as shown in Fig. 1, which have the obvious characteristic of a common node in the centre of the divider.…”

“…Connectors are necessary to connect cables in such systems. The modeling of SMA connectors is either neglected in the simulation of microwave components or approximated by an inaccurate model to model its characteristics .

The modeling of subminiature version A (SMA) connectors is occasionally neglected when simulating microwave components or when an approximated model is used to represent its characteristics. In this article, SMA connector modeling is investigated and an appropriate simulation modeling is discussed. It was observed that modeling the inner part of the SMA connector using the coaxial cable model is adequate when no electromagnetic field exist outside of the SMA connector. However, modeling the exterior structure including a receptacle, if it exists, is required when an electromagnetic field exist outside the connector. © 2015 Wiley Periodicals, Inc.
