A comprehensive 5G system design methodology targeting 1Gbits/s next generation cellular communication is presented with associated design trade-offs. With an emphasis on beamforming to overcome mm-wave propagation challenges, a systematic link budget analysis has been carried out from 3GPP 5G NR standards to derive individual specifications for an RF front end module and RFIC. A detailed analysis of the effect of non-idealities on key figure of merits for receive and transmit chains is presented. Practical beamforming simulations is performed using a 2X4 dual polarized patch antenna array. It is also demonstrated that floorplan, power and thermal requirements play an important role in terms of decisions on technology-nodes, package-substrate selection and heterogenous integration. © 2019 IEEE.

System Budget to System Realization-A 5G mm-wave Beamformer Perspective

Proceedings of the 2019 21st International Conference on Electromagnetics in Advanced Applications, ICEAA 2019

A low power, high gain 28GHz mm-wave two stage cascaded CG-CS LNA in a 45nm bulk CMOS process is reported for low power 5G RF beamformers. High gain in the LNA is essential in RF beamformers to compensate the loss from passive phase shifters unlike a hybrid beamformer. To achieve high gain, low NF and low power consumption, the first stage utilizes the concept of passive gm boosting in a CG cascoded stage coupled with series peaking. A regular CS cascoded 2ndstage boosts gain further. Post-layout EM simulations predict a gain of 32dB and a noise figure of 3.3dB at a power consumption of only 7mW. As a proof of concept, a traditional two stage cascoded CS LNA has also been implemented utilizing slow wave transmission lines to highlight a 3X increased power consumption with similar small signal gain and NF. An IC, package and PCB co-analysis methodology for such mmwave blocks is also introduced as it becomes essential to verify the chip in context of Package/PCB before tapeout. © 2019 IEEE.
