In this paper we propose a baseband noise-canceling receiver architecture to increase in-band linearity. Key feature of the architecture is that all active circuits are in baseband, including the LNTA. The receiver targets high IF bandwidths, enabled by a TIA composed of an OpAmp using only inverters. The receiver is fabricated in 22nm FDSOI CMOS. Measured results show an in-band IIP3 of > 9dBm for an IF bandwidth of 175MHz with sub-5dB NF across 1-6GHz LO.

“…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.

“…The RF modulator consists of all analog/RF functionality of the TX except actual PA, RF filtering, and switches (RF front-end, RFFE) required before the antenna. Based on a recent example in [19], even an EVM of 0.5% would be possible for a BS TX. Correspondingly, somewhat lower EVM of ~1% has been reported for an IC targeted for mobile applications [20].…”

Abstract-Wideband fifth generation (5G) systems utilizing high carrier frequency and multiple-input multiple-output (MIMO) raise major challenges for the system design. Wave propagation and practical hardware tradeoffs at higher frequency ranges provide new boundary conditions for the implementation. This paper addresses system performance boundaries and the analysis method towards multibeam communications at mmW. We combine analysis from antennas and propagation to the RF transceiver specifications and beamforming requirements. Realistic propagation model and antenna implementation is used to generate beam-specific path gains and provide a wide variety of user scenarios. Using this approach, system level interdependencies and RF performance boundaries can be verified with different antenna configurations in various propagation environments. As an example, we present MIMO link budget analysis targeting 10 Gbits/s for multiple devices in the office scenario at 27 GHz.
