“…There are various types of power splitters such as transformer type Wilkinson splitter, lumped element quadrature Wilkinson power splitter, hybrid splitter, phase splitter, and mixed lumped distributed element power splitter. Power splitters are designed to fit some standard frequency ranges such as low frequency (120-135 kHz), high frequency (10)(11)(12)(13)(14)(15), ultra high frequency (UHF) (850-950 MHz), and microwave frequency (2.45 GHz) [2]. Nowadays, scientists are making power splitter using various processes and technologies to achieve low losses, low costs and to minimize the area.…”

In order to use power splitter for communication and real world applications (e.g., telephony performances, antenna designs, wireless communications, digital communications, optical communications, CATV transmission systems, airborne systems), studying the nature and characteristics of the splitter is important. The purpose of this paper is to review and discuss various techniques aimed to develop the power splitters component and remove its interference. This paper further focuses on the review of future implementation techniques and performance comparison along with their applications. Some of the applications are illustrated at the end of the paper, and recommendation for further study is also outlined. This review serves as a comparative studies and reference beneficial for power splitter researchers and for future implementation of the technology. This review paper opens a corridor for researchers to perform future comparative studies between different architectures and models as a reference point for developing more powerful, flexible and efficient applications.

In order to satisfy the power thirsty of communication devices in the imminent 5G era, wireless charging techniques have attracted much attention both from the academic and industrial communities. Although the inductive coupling and magnetic resonance based charging techniques are indeed capable of supplying energy in a wireless manner, they tend to restrict the freedom of movement. By contrast, RF signals are capable of supplying energy over distances, which are gradually inclining closer to our ultimate goal -charging anytime and anywhere. Furthermore, transmitters capable of emitting RF signals have been widely deployed, such as TV towers, cellular base stations and Wi-Fi access points. This communication infrastructure may indeed be employed also for wireless energy transfer (WET). Therefore, no extra investment in dedicated WET infrastructure is required. However, allowing RF signal based WET may impair the wireless information transfer (WIT) operating in the same spectrum. Hence, it is crucial to coordinate and balance WET and WIT for simultaneous wireless information and power transfer (SWIPT), which evolves to Integrated Data and Energy communication Networks (IDENs). To this end, a ubiquitous IDEN architecture is introduced by summarising its natural heterogeneity and by synthesising a diverse range of integrated WET and WIT scenarios. Then the inherent relationship between WET and WIT is revealed from an information theoretical perspective, which is followed by the critical appraisal of the hardware enabling techniques extracting energy from RF signals. Furthermore, the transceiver design, resource allocation and user scheduling as well as networking aspects are elaborated on. In a nutshell, this treatise can be used as a handbook for researchers and engineers, who are interested in enriching their knowledge base of IDENs and in putting this vision into practice.Index Terms-RF signals, wireless energy transfer (WET), wireless information transfer (WIT), simultaneous wireless information and power transfer (SWIPT), wireless powered communication networks (WPCNs), integrated data and energy communication networks (IDENs).an increasing research interest from both the electronic and communication engineering communities. C. Near-field Wireless Energy TransferAt the time of writing, resonant inductive coupling [35] and magnetic resonance coupling [36] emerge as flexible wireless charging options for electronic devices in the nearfield. Resonant inductive coupling based wireless charging relies on the magnetic coupling that delivers electrical energy between two coils tuned to resonate at the same frequency. This technique has already been commercialised for small electronic appliances [37], such as mobile phones, electric toothbrushes and smart watches etc. However, the coupling coils only support near-field wireless power transfer over a distance spanning from a few millimetres to a few centimetres [38], while achieving a power transfer efficiency as high as 56.7%, when operating at a frequency of 508 kHz [...
