With more upcoming frequency bands used for wireless communication, there is a growing need for transmitters and receivers that can operate at different frequencies in a flexible way. In this presentation a forgotten technique called N-path filters is highlighted, and examples of flexible channel filtering using this technique directly at RF are given. 10:15 Peter Baltus (Technical University Eindhoven)

Unconventional Wireless Applications


Although it might be hard to believe, there are actually wireless applications beyond 5G. Some of them are rather unconventional if not downright weird, and for some reason I tend to get involved in projects exploring technologies for such applications more often than could be expected on a purely statistical basis. In this presentation I’ll discuss some of these applications and the related technologies that we’re working on. 10:45 break

Polymer Microwave Fibers: who's waiting for it?


Using polymers or plastics as a flexible guided dielectric channel, together with mm-wave signals and Silicon chips, was recently proposed as a complementary alternative to optical and copper. Often referred to as Polymer Microwave Fibers (PMF), the mechanical robustness and EMI tolerance are key differentiators for this communication approach. Compared to optical communication, no EO/OE conversion is needed since the mm-wave signal is directly launched into the fiber with an antenna. Furthermore, the connectors have a much higher robustness compared to optical connectors. Compared to copper wireline, far less EMI issues arise since no metal is being used in the channel. Several demonstrators have been developed both at Universities and companies, revealing the strengths and weaknesses of this approach. This presentation will give an in-depth discussion of the topic, discuss some of the implementation challenges and will give a good understanding of the benefits and drawback of PMF, and conclude with an outlook of the future of PMF. 11:45 Leo de Vreede (Technical University Delft)

Digital Transmitters for Sub-6GHz Wireless Applications


Digital-intensive transmitters (TX) concepts are rapidly gaining interest, since they can convert the high-speed digital baseband data directly into the transmitting RF signal, while allowing very compact and cost-effective integration. In addition, their digital (switching) nature opens up (new) possibilities in achieving high energy efficiency, spectral purity and frequency-agile operation. This talk will describe the strengths, challenges and promises of these digital inspired TX solutions for mMIMO applications and sub-6GHz wireless Applications.

Listen to your gut: swallable digital transmitter design


Swallable smart pills are going to revolutionize the next-generation diagnosis tool of the digestive tract. This talk will introduce the design challenges of the RF transceiver targeted for such applications. A case study on an ultra-low power and digital-intensive RF transmitter will also be provided." 13:30 wrap-up Kofi Makinwa (Technical University Delft)
