“…In this work, a GaN transistor based two-stage Class-AB/J PA has been designed and simulated at an operating frequency of 3.5GHz (i.e., sub-6GHz). As the selection of operating frequency for proposed PA is also an important consideration, various frequency bands such as LTE & 5G new radio (NR) [24]- [26] are analysed for appropriate selection of proposed PA's operating frequency and BW. Based on the analysis, a new sub-6 GHz frequency band with a centre frequency of 3.5GHz, called Citizen Broadband Radio Service (CBRS) [27] will be the appropriate choice for 5G wireless communications of AMI in a smart grid.…”

The wireless communication networks for Advanced Metering Infrastructure (AMI) / smart metering applications of a smart grid are in need of emerging 5G technology for providing a significant enhancement in bandwidth (BW) to support a large amount of data transmission between the Meter data management system (MDMS) of operation centre and smart meters efficiently. The entire wireless communication network’s BW and efficiency mainly depend on its Power Amplifier (PA). The design of PA that can provide high efficiency with linearity over a wide BW is essential to meet the 5G wireless communication network requirements of AMI / smart metering applications. This paper presents the design methodology of a two-stage PA that operates at a 3.5 GHz centre frequency by utilizing the CGH40010F model GaN transistor. This PA employs a Class-J mode for the power stage that will be driven by a Class-AB mode to achieve high efficiency with improved power gain over desired BW. The matching Networks(M.Ns) of the proposed two-stage PA are designed with the idea to replace its passive lumped inductors with active inductors, based on the desired optimum impedance values obtained from the load-pull techniques utilizing the ADS EDA tool. The proposed two-stage PA delivers a power output of 41dBm with 21 dB of power gain over a BW around 400 MHz, a maximum Power Added Efficiency (PAE ) of 53% and maximum drain efficiency (D.E) of 54% with a small signal gain of 27dB at 3.5GHz using 28V power supply into 50 Ω load.

“…However, the important point to be considered when designing a PA for these smart grid applications is the frequency at which it has to be operated. Hence, different frequency bands, including LTE and 5G NR (new radio), [26][27][28] are analyzed to choose the appropriate operating frequency of the proposed Class-J PA. Recently, a frequency band termed citizen broadband radio service (CBRS) with 3.5 GHz center frequency (i.e., 5G sub6 GHz frequency) was allocated for public usage.…”

Background: With the tremendous increase in the usage of smart meters for industrial/ household purposes, their implementation is considered a crucial challenge in the Internet of Things (IoT) world, leading to a demand for emerging 5G technology. In addition, a large amount of data has to be communicated by smart meters efficiently, which needs a significant enhancement in bandwidth. The power amplifier (PA) plays a major role in deciding the efficiency and bandwidth of the entire communication system. Among the various modes of PAs, a newly developed Class-J mode PA has been proven to achieve high efficiency over a wide bandwidth by maintaining linearity. Methods: This paper proposes a Class-J mode PA design methodology using a CGH40010F-GaN device that operates at a 3.5 GHz frequency to meet the requirements of 5G wireless communication technology for the replacement of existing 4G/LTE technology used for advanced metering infrastructure (AMI) in smart grids. This research's main objective is to design the proper matching networks (M.Ns) to achieve Class-J mode operation that satisfies the bandwidth requirements of 5G smart grid applications. With the target impedances obtained using the load-pull simulation, lumped element matching networks are analyzed and designed in 3 ways using the ADS EDA tool. Results: The simulation results reveal that the proposed Class-J PA provides a maximum drain efficiency (D.E) of 82%, power added efficiency (PAE) of 67% with 13 dB small-signal gain at 3.5 GHz, and output power of 40 dBm (41.4 dBm peak) with a power gain of approximately 7 dB over a bandwidth of approximately 400 MHz with a 28 V power supply into a 50 Ω load. Conclusion: The efficiency and bandwidth of the proposed Class-J PA can be enhanced further by fine-tuning the matching network design to make it more suitable for 5G smart meter/grid applications.

Abstract. Smart grid allows two-way communication between power utility companies and their customers while having the ability to sense along the transmission lines. However, the downside is such, when the smart devices are transmitting data simultaneously, it results in network congestion. Fiber wireless (FiWi) network is one of the best congestion solutions for smart grid up to date. In this paper, a survey of current literature on FiWi for smart grid will be reviewed and a testbed to test the protocols and algorithms for FiWi in smart grid will be proposed. The results of number of packets received and delay vs packet transmitted obtained via the testbed are compared with the results obtained via simulation and they show that they are in line with each other, validating the accuracy of the testbed.
