The growing demand for high data rate, longer battery life and low latency is pushing the transition from 4G Long-Term Evolution (LTE) to 5G. There is a partition of the 4G/5G RF systems using advanced low feature nodes for 4G/5G modems and transceivers and the other RF and analog functions being integrated into several Front End Modules (FEMs). The FEMs will integrate power amplifiers, switches, couplers, tuners and active acoustic filters. These will cover more than 50 LTE bands from 600MHz to 6GHz as well as mm-Wave. The short course will cover practical design aspects for 5G FEMS with emphasis for FEM architectures, power amplifiers, switches and active filters as well the technologies involved in these designs. The course will cover also aspects of new 5G LTE integration for envelope tracking and LNA design.

5G is a big leap from 4G unlike the small incremental performance improvements from previous cellular generations. For example, the data rate, latency, reliability and device density are targeted 100 times better than 4G. 5G new radio (5G NR) has opened up a huge window of opportunity even for the non-legacy players in the cellular,   especially mm-wave arm of 5G called 5G NR (FR2). The challenges thrown are hitherto unknown to the legacy players and the opportunity is fair to everyone. The opportunities are not only in the mobile but also on the infrastructure with the more than an order of increase in base stations.


Through this course, the system-level requirements, and the challenges thereof will be first introduced. The component level requirements including the architectural and technological challenges will be discussed. Example solutions will be demonstrated to highlight the trade-offs. The state of the art solutions will also be discussed. Finally, the testing challenges and solutions will be outlined as well. 

The topics will include:

  1. Architectural choices for mobile, user equipment (UE), BSUs (small cells, picocells, femtocells, repeaters
  2. Various beam formers schemes like Digital, Analog and Hybrid beamforming
  3. Circuit level implementations of (a) analog beamformer (Phase shifters, VGA, LNA, PA and RF switches, antennas including antenna in a package), Modems including the reconfigurable radios
  4. Fronthaul architectures to meet the end to end latency of 1 msec including radio over Fiber (RoF) and Backhaul architectures
  5. Integration of satellite communications with 5G

Room: Orchid 4211

Date: 10 December 2019                                                                                                                                                                                 Time: 0830hrs - 1200hrs (Tea Break 10:00hrs - 10:30hrs)

Multi-Beam Antennas (MBAs) find application in several fields including wireless and satellite communications, RADARs for electronic surveillance and remote sensing, science (e.g. radio telescopes), RF navigation systems, etc. Beam-Forming Networks (BFNs) play an essential role in any antenna system relying on a set of radiating elements to generate a beam. Depending mainly on the antenna mission different MBA architectures may be selected: from antenna systems completely based on independent feeds illuminating a number of reflectors, to hybrid systems based on both arrays and reflectors, from phased arrays to lens antennas. The trade-off on the antenna solution largely involves the BFN interconnectivity and flexibility requirements, with a wide range of applicable BFN architectures with different complexity and performance.

The objective of the course is to present design principles and state-of-the-art in MBAs and BFNs. The course presents design principles and state-of-the-art in Multi-Beam Antennas (MBAs) and Beam-Forming Networks (BFNs) covering both theoretical and practical aspects.

Short Course Title: Resonant Measurement Methods of Dielectric and Ferromagnetic Materials in Microwave and mm-wave Spectra

The following subject will be introduced:

  1. Measurements of in-plane permittivity with split-post dielectric resonators (SPDR) in the 1-15 GHz range. The theory of operation of SPDRs and their practical use will be addressed with the emphasis on the advantages and limitations of the method.
  2. Measurements of in-plane permittivity with a Fabry-Perot open resonator (FPOR) in the 20-110 GHz range. Special attention will be focused on a new electromagnetic model of the resonator based on a conformal transformation technique.
  3. Measurements of out-of-plane permittivity with a cylindrical resonator in the microwave range. It is of essential importance in the design of microwave circuits.
  4. Measurements of the soil moisture in a cylindrical resonator. The particular application of the permittivity measurements in the extraction of the soil moisture will be discussed.
  5. Measurements of a ferromagnetic linewidth of ferromagnetic materials in the microwave range. A new accurate approach based on mode splitting will be addressed.
