This paper presents and compares two transformerless Series Doherty Power Amplifier (SDPA) architectures that are designed with a Wilkinson and Active balun power driver for 5G Vehicle-to-everything (V2X) communication.The proposed SDPAs utilize LC balun to set gate-source voltage of main Power Amplifier (PA). The innovative use of a balun as a replacement for the transformer in both proposed SDPA architectures has demonstrated improved reliability while also designs with reduced area and cost of the system. Additionally, lumped elements are used instead of the bulky λ/4 transmission line which used for the load modulation. Compared to the conventional parallel Doherty power amplifiers, the proposed SDPAs achieve reduced area designs. The SDPAs were designed and simulated using the 65 nm CMOS process at a frequency of 5.9 GHz. The power gain of the SDPA, which uses the Wilkinson power divider, is 12.65 dB. The SDPA also exhibits a power-added efficiency (PAE) of 23.8% and a drain efficiency (DE) of 29.45%. The compression point (P-1dB) of the SDPA is 10.3 dBm. The SDPA using the Active balun delivers a power gain of 21.66 dB, a PAE of 16.77%, a remarkable DE of 41% indicating a high degree of efficiency. The compression point (P-1dB) of this SDPA is 15.6 dBm.

This article presents advancements and key considerations in the design implementation of phased array transceivers for the fifth-generation (5G) communication networks. It emphasizes the significance of careful consideration and system-level optimization to realize the full potential of phased array transceivers. The focus is on antenna elements and beamforming techniques with a detailed discussion on different types of beamforming techniques used in wireless communication systems. These include analog, digital, and hybrid beamforming. The article starts by introducing the concept of a phase shifter, which is a crucial component in controlling the phase of the transmitted signal. It then proceeds to discuss the role of a variable gain amplifier in amplifying the signal received by each antenna element of the array, followed by emphasizing the importance of a Low-Noise Amplifier (LNA) in transceiver design to amplify weak signals with minimal noise. In addition, this article provides a detailed discussion on the mixer, which is used to downconvert or upconvert the frequency of the received signal to a more appropriate frequency for further processing or transmission. Finally, the power amplifier (PA), which is used to boost signal power in 5G networks, is also discussed in detail.
