“…However, such designs suffer from a limited band ratio. Some of the efforts were based on Π‐ and T‐configurations or coupled lines . Moreover, although topologies utilizing R , L , and C lumped components in their isolation networks provide a higher band ratio, these designs have limited use at high frequencies due to their inherent parasitics .…”

The complexity of RF front-end (RFFE) modules of wireless devices has increased dramatically over the past decade. In order to meet the demands for future mobile communications, RFFEs will need to enable multiband for global roaming, and multi-mode to support multiple cellular modes, incorporate beamforming antennas, and operate at mm-wave frequencies. To this end, this article presents a summary of the recent progress in RF substrate technologies, waveguide architectures and multi-band design techniques for 5G RFFE modules, and summarizes the present and future challenges in RFFE module design.

“…In , the length of the extended output ports was coupled to widen the range of the frequency ratio of dual bands at the cost of degraded isolation. Adding an isolation stub between the isolation resistor and the output ports can considerably reduce the parasitic effects of transmission lines . In , a novel three‐way power divider was proposed, in which a half‐loop stepped‐impedance resonator was used to realize the coupling between the input and the output ports.…”

Dual‐band Wilkinson power dividers were constructed using I‐shaped lines. Inserting a stepped‐impedance stub in the middle of the lines could induce a shunt susceptance to achieve dual‐band 90° operation. The proposed circuit structure and synthesis equation had two degrees of freedom which could be exploited to reduce the impedance and length of the lines. An experimental 2.4/5.2 GHz Wilkinson power divider was demonstrated. The measurement shows S21 = −3.24 dB and S31 = −3.21 dB at 2.4 GHz and S21 = −3.26 dB and S31 = −3.37 dB at 5.2 GHz. The measured isolation level was 35.95 dB (2.4 GHz) and 36.57 dB (5.2 GHz). © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2034–2037, 2015

“…However, the utilized structure is difficult to integrate with the other microstrip-based devices. The use of different types of shunt stubs or coupled lines results in a narrowband performance (Li et al, 2009bWu et al, 2010;Ahn et al, 2009).…”

Analysis and Design of Ultra-Wideband Unequal-Split Wilkinson Power Divider Using Tapered Lines Transformers

An ultra-wideband unequal-split Wilkinson power divider with a 2:1 split ratio is presented. To achieve the ultra-wideband characteristics, the conventional quarter-wave arms of the divider are replaced by tapered lines. Moreover, two extra tapered transformers are incorporated at the output ports for matching purposes as the designed divider is of an unequal-split type. To obtain good isolation between the output ports, five isolation resistors are used, the values of which are determined using the simple odd-mode analysis of the Wilkinson power divider. For verification purposes, an ultra-wideband Wilkinson power divider that operates over a frequency range extending from 2 to 12 GHz is designed, simulated, fabricated, and measured. The results of the full-wave simulation and measurements verify the validity of the design procedure.
