This article presents a comprehensive survey of the literature on self-interference (SI) in long-term evolution advanced (LTE-A) and fifth-generation (5G) new radio transceivers and should serve the reader as a guide and starting point for further work on SI management. Current trends in cellular transceiver designs are discussed, and reasons why new technologies, such as carrier aggregation, cause potential sensitivity degradation due to self-interfering signals are highlighted. The survey provides an overview of the most common interference mechanisms and continues with a taxonomy on SI mitigation architectures by comparing the strengths and weaknesses of various techniques.

“…Depending on the system requirement and the IQ modulator performance one may need bandpass filters as well before proceeding to the output. Complete integrated transceivers (also called bits-to-RF) in deep submicron CMOS process for multiple channels and multiple carriers, are recently reported by different commercial vendors [78,63,76,79,59]. Some of these complete system-on-chip transceivers are claimed to support all different cellular standards in macro base stations.…”

The network latency in fifth generation mobile technology (5G) will be around one millisecond which is much lower than in 4G technology. This significantly faster response time together with higher information capacity and ultra-reliable communication in 5G technology will pave the way for future innovations in a smart and connected society. This new 5G network should be built on a reasonable wireless infrastructure and 5G radio base stations that can be vastly deployed. That is, while the electrical specification of a radio base station in 5G should be met in order to have the network functioning, the size, weight and power consumption of the radio system should be optimized to be able to commercially deploy these radios in a huge network. Last but not least I would like to especially thank my soulmate and my love Hoda. Without all your help, your devotion and patience, I would not be able to complete this work. Therefore, I dedicate this work to you.

“…There are several 5G NR transceiver architecture options for user equipment such as RF, baseband (BB), and intermediate frequency (IF) interfaces [1]- [10]. The IF interface is the most realistic choice and widely employed in mobile platforms owing to the lower loss and ease of matching at the IF signal frequency [1], [3], [4], [6]- [9]. One chip solution, including 5G NR sub-6 GHz frequency range 1 (FR1) and mmWave IF transceiver, can also be used to implement low-cost and highly integrated IF interface option [4].…”

In this paper, a 24-40 GHz broadband millimeter-wave (mmWave) down-conversion doublebalanced mixer with a dual-band local oscillator (LO) buffer employing RF and IF coupled resonators is presented for 5G new radio (NR) frequency range 2 (FR2) cellular applications. The proposed mixer comprises a transformer-coupled gm-boosted common-gate (CG) Gm-stage, a single-to-differential currentto-current RF capacitor-tuned coupled resonator, active switching stages with dual-band three-stage LO buffers, a current-to-voltage IF coupled resonator with gain equalization, and a wideband IF buffer with a transformer-based balun. The transformer-coupled gm-boosted CG Gm-stage improves the NF and provides broadband input power matching. RF and IF coupled resonators enable an RF operating frequency range of 24-40 GHz and IF 1 dB bandwidth of more than 0.8 GHz, respectively. The implemented mixer was fabricated using a 40 nm CMOS process and characterized primarily in the 5G NR FR2 bands. The active die area was 0.654 mm 2 , and the mixer drew a bias current of 16 mA from a nominal supply voltage of 1.1 V. The mixer exhibited an RF operating frequency range of 24-40 GHz, noise figure of 12.4 dB, conversion gain of 1.2 dB, IF 1 dB bandwidth of 1.1 GHz, and output-referred third-order intercept point of 6.8 dBm.INDEX TERMS 5G, broadband, capacitor-tuned, cellular, coupled resonator, frequency range 2 (FR2), down-conversion mixer, dual-band, gain equalization, gm-boosted, LO buffer, millimeter-wave (mmWave), new radio (NR)
