“…As presented in [22,23] this structure can be used with a differential transformer/balun. In [24] a HPUE PA with an ET has been presented. Using the same approach, a high resistivity CMOS 0.18 μm PA with a push-pull class E output stage and integrated fast error amplifier is presented in Fig.…”

“…For both implementations there is a penalty in terms of size using an IPD balun. At LBs (400-1200 MHz), using a balun helps with the second harmonic suppression for coexistence with other 5G transmitters and mitigates the low breakdown voltage for CMOS devices [24,30]. For size constrained applications, which is the case for 5G smartphones, the use of IPD baluns becomes practical for higher FR1 frequencies, such as n41, n77, n78, and n79 or FR2 mmWave frequencies.…”

Worldwide adoption of fourth-generation wireless (4G) long-term evolution (LTE) smartphones and the actual transition to fifth-generation wireless(5G) is the main driving engine for semiconductor industry. 5G is expected to reach high data rate speeds (1 Gbps) and low latency (<1 ms). 5G requires more RF bandwidth and therefore an increase in the number of components such as RF switches, acoustic filters, and power amplifiers integrated in few RF front-end modules. Also, there is an increase in the number of RF radio transmitters and receivers operating at the same time. This paper presents new architecture elements for 5G RF front-end modules. Circuit details and measurements are presented to reduce the RF noise, improve the efficiency, and help the coexistence of multiple radio transmitters. These circuits will help extend the 5G applications with radar-like sensing applications, remote medicine, and autonomous driving.

“…Other high performance technologies, such as ultra-wideband (UWB), RF sensing and Internetof-Things are participating in development of 5G/6G long term evaluation (LTE) platform [3], [4]. Therefore, the RF front-end (RF-FE) integration of transceiver modules, such as power amplifier, LNA, RF switches and MIMO antennas is needed under single substrate [5], [6]. To design successful RF-FE, a versatile electronic design and automation (EDA) simulation tool is required.…”

Fifth generation (5G) wireless communication systems demand compact and low-profile high gain wideband antenna. Planar log-periodic array antenna (pLPA) has such potential qualities for 5G base-station and user-devices. However, many important features and RF analysis are rarely elaborated for pLPA which include equivalent circuit modeling. In this article, authors present the systematic RF analysis, fabrication, and equivalent circuit modeling for sub-6GHz 5G application using theory of characteristic modes (TCM). The fabricated pLPA designed to cover the 5G bands with a high gain of > 5 dBi and a fractional bandwidth of > 1. Using simulation tool based on method of moments, radiating and nonradiating modes are tracked and studied with detailed physics. These modes are modelled using analytically derived equivalent circuit and assembled in an RF/microwave circuit simulator. The characteristic mode analysis and RF circuit modeling of pLPA help in the advancement of future 5G RF front-end modules.
