This course is day 5 of the 5G New Radio Specifications and System Design course and can be taken on its own or as part of the 5-day course.

This session presents an overview of state of the art solutions and strategies used by chipset vendors to deliver cost efficient LTE and 5G terminals, with a focus on the RF subsystem and RF Front-End architectures.

Supporting the increasing number of bands and band combinations, maintaining radio performance, hardware cost and power consumption in multi-mode multi-standard smartphones poses serious design challenges

Programme details

This session presents an overview of state of the art solutions and strategies used by chipset vendors to deliver cost efficient LTE-A Pro and 5G terminals/User Equipment (UE) with a focus on the RF subsystem and RF Front-End architectures.

Supporting the increasing number of bands and band combinations, maintaining radio performance, hardware cost and power consumption in multi-mode multi-standard smartphones poses serious design challenges. This course is a hands-on session looking at printed circuit boards (PCB), block diagrams and RF architecture solutions used by OEMs and chipset vendors to accommodate an ever increasing of frequency bands at near constant PCB area and BOM. Laboratory and field measurements are presented to compare 3GPP conformance tests vs real life operation and to illustrate end to end system performance for HSPA, LTE, LTE-A and VoLTE.
