In this article, a new structure of power divider (PD) is presented. This design shows high‐power handling capability, enhanced selectivity performance, and simple structure. Theory analysis based on impedance matching method has been performed. The closed‐form design equations and detailed design procedure have been given and summarized at the same time. For verification purpose, a prototype with a center frequency of 2.5 GHz is simulated and fabricated, and the measurement results show a good agreement with the simulated ones.

This article presents for the first time a quad‐band Gysel power divider capable of achieving equal and unequal power division at four arbitrary frequencies. The structure of the proposed divider is similar to its single‐band counterpart but loaded with quad‐band reactive networks. The design procedure and theoretical analysis of the proposed divider are presented. A quad‐band Gysel power divider with equal division and another with 2:1 unequal division are designed at the operational frequencies of 0.85, 1.6, 2.4, and 3 GHz. Simulation and measurement results of the two dividers are presented, and good performance is observed at each band. For both designs, the realized power division ratios are within 1 dB from their ideal values, whereas the matching and isolation levels are below −10 dB at the four bands.

Based on the double‐sided parallel‐strip lines with an inserted conductor as a virtual ground, a high power divider with dual‐band/broadband response and frequency‐independent 180° phase difference between the output ports is implemented in this paper. The circuit topology employs a single commercially available external isolation resistor as well as moderate line impedances (15–100 ohm), making it suitable for high‐power applications. Precise closed‐form design equations on the basis of even‐ and odd‐mode analysis are derived. In addition to the wide range of frequency band ratios from 1 to 2.65, broadband response is also obtained by selecting the proper value of frequency band ratios. To substantiate the design equations and theory, a circuit with 2:1 frequency ratio and 84.5% bandwidth referring to 16 dB isolation and 12 dB return loss values is developed. To the authors' knowledge, this is the widest bandwidth reported for out‐of‐phase high power dividers. © 2016 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2016.
