“…Increasing demands for long‐range communication, including radar, commercial, and satellite communications have necessitated the development of power combining techniques that can provide higher output power than what is available from a single amplifier. Various power combining techniques have been introduced to satisfy this need . However, component failure causes imperfect summation of power and results in the degradation of output power level.…”

A four‐way switchable power combiner/divider is proposed in this letter. The structure is based on a substrate integrated circular cavity, and control of the number of coupling probes is possible for graceful degradation. The proposed structure forms a switchable power combining circuit with amplifiers at 2.13 GHz. In addition, the proposed scheme provides improved graceful‐degradation performance under the condition of amplifier's failure. The graceful‐degradation characteristics of gain and output power are experimentally demonstrated as one or more amplifiers are switched off. © 2015 Wiley Periodicals, Inc.

“…They can also be used in amplifier circuits to combine power. Many microstrip or waveguide multiport power dividers, which can be divided into two categories (i.e., sector and radial), have been reported in the literature [1][2][3][4][5][6][7][8][9][10]. The former employs chain or tree structure to realize a multiport power divider, while the latter just needs to enlarge the radius of the configuration which can reduce the whole size of a power divider.…”

A wideband microstrip planar radial 1:19 power divider is developed in this study. The power divider design is simple with conventional impedance-transformation method, and a single substrate is employed, thereby reducing the cost for the antenna. To verify our design, the power divider was fabricated and tested. It can be observed that it achieves an impedance bandwidth of 29.4% (1.98 GHz-2.67 GHz) (VSWR 2), the transmitted magnitude and phase imbalance for 19 outputs are ± 0.1 dB and ± 1 deg, respectively. The power divider is also integrated into the 19-element circularly polarized (CP) antenna array as the feed network; the simulated results show that the power divider can apply appropriate amplitudes and phases for the antenna array to obtain the good CP performance.

“…In these designs, waveguide‐based power dividers have been widely investigated and used in microwave and millimeter‐wave systems because of their low insertion loss and high‐power capability. Several waveguide‐based power dividers/combiners, such as ring‐cavity power divider , substrate integrated waveguide power dividers , radial waveguide power dividers , and coaxial waveguide power dividers have been studied, and some good performance is reported. Besides, the planar power dividers always have compact size and easy to be integrated, which made them widely be used in RF/microwave systems.…”

Compact filtering power divider with good frequency selectivity and wide stopband based on composite right‐/left‐handed transmission lines

A novel compact power divider with good frequency response and wide stopband based on composite right-/left-handed (CRLH) transmission line is presented in this article. To provide bandpass-filtering frequency response, the bandpass filtering circuits is applied to this power divider using the CRLH resonators. The bandpass filtering circuit can generate two transmission zeros at the lower and upper stopband and have a wide upper stopband. Besides, the phase shift of the CRLH filter is tuned to be 90 for the sake of replacing the conventional quarter-wave length branch line in the power divider. Moreover, the capacitive coupling between the input and output of the resonator is used simultaneously to generate three additional transmission zeros beside the passband edges. Then, the frequency selectivity of the power divider is greatly improved. A resistor is placed at the center of the symmetric plane to produce good isolation between the two outputs. A filter-integrated power divider operating at 3.7 GHz is implemented. Good agreement between the simulated and measured results is observed.
