“…It is widely known that the RF PA is the most power-hungry component in radio transceivers, and is one of the most critical building blocks in radio frontend. Hence, research in this area will help drive overall 5G network costs down while achieving improved energy efficiency (Cheng et al, 2015). Moreover, as technology advances, digital circuits can replace more and more analog circuits in the RF transceivers.…”

“…Hence, research in this area will help drive overall 5G network costs down while achieving improved energy efficiency. A research study has been conducted in [9], which focused on investigating the development trend of RF PAs and describing the globalization, cooperation across affiliations, research cycle and architecture trends. Figure 2 presents an updated graph published in [9] adding traveling wave (TWA) and distributed PA to the overall number of published PA papers and the trend line picture.…”

“…Various advanced PA architectures have been proposed throughout the years and demonstrated for increasing RF PA efficiency without losing linearity or even with improved linearity, including envelope elimination and restoration (EER), envelope tracking (ET), linear amplification using nonlinear components (LINC) and Doherty (DPA) [9]. Two more RF PA architectures that have a huge impact on modern RF PAs haven't been mentioned in [9] and are named TWA and distributed PA. Frequency band allocations in USA, Europe and Asia (only China and Japan are included) can be divided into three regions: low frequency (600-700 MHz), high frequency (2.5-7 GHz) cells as well as millimeter wave cells (above 24 GHz).…”

“…Originally proposed in early 1936 by W. H. Doherty, the widely adopted and thoroughly investigated, DPA was resurrected at the beginning of this century [39]. In spite of more than 80 years from its introduction, the DPA actually seems to be one of the best candidates to realize PA stage for current and future generations of wireless systems [9]. The Doherty power amplifier is based on the active load concept, to suitable modulate (decrease) the impedance termination of an active amplifying device, thus forcing the latter to operate at its maximum efficiency condition for a pre-determined range of input and/or output power levels.…”

The structure of the modern wireless network evolves rapidly and maturing 4G networks pave the way to next generation 5G communication. A tendency of shifting from traditional high-power tower-mounted base stations towards heterogeneous elements can be spotted, which is mainly caused by the increase of annual wireless users and devices connected to the network. The radio frequency (RF) power amplifier (PA) performance directly affects the efficiency of any transmitter, therefore, the emerging 5G cellular network requires new PA architectures with improved efficiency without sacrificing linearity. A review of the most promising reported RF PA architectures is presented in this article, emphasizing advantages, disadvantages and concluding with a quantitative comparison. The main scope of reviewed papers are PAs implemented in scalable complementary metal–oxide–semiconductor (CMOS) and SiGe BiCMOS processes with output powers suitable for portable wireless devices under 32 dBm (1.5 W) in the low- and high- 5G network frequency ranges.

In this paper, the impact of the bias networks on a radio frequency (RF) power amplifier (PA) is analyzed and discussed comprehensively. Both the different sizes and positions of the bias microstrip line circuit have been studied for a broadband class AB PA. Both simulations and measurements show that the performance of the PA can be greatly improved with the adjustment of the bias circuit by effecting the harmonic impedance of the whole matching circuit. Compared with the existing works, the fabricated PA based on the proposed technique provides the best performance, thereby demonstrating the effectiveness of the developed bias circuit optimization method.
