Designing for the future
Exploring the challenges and possibilities of designing to 300 GHz
T
he world of RF (Radio Frequency) and mmWave (millimetre-wave) communications is rapidly advancing toward harnessing the potential of
ultra-high frequencies, reaching 300 GHz and beyond. Tis journey, while filled with promise, is laden with challenges. Here, Tudor Williams, Director of Technology at designer and manufacturer of RF-to-mmWave components and subsystems, Filtronic, explores the considerations involved in designing and manufacturing at 300 GHz, delving into the difficulties, evolving technologies and the need for innovation to make this a reality. Te Internet has become an integral part of our daily lives, facilitating
By Tudor Williams, Director of Technology, Filtronic activities such as information exchange, social networking, banking and online shopping. As we step further into the era of the Internet of Tings (IoT), where a web of smart devices seamlessly connects, the possibilities are endless. Tese IoT applications are poised to reshape everything from the way that our households run to modern businesses and manufacturers. To meet these needs and keep up with
the ever-increasing demand for data, 5G and 6G wireless networks must push the boundaries further, the most likely early implementations of these higher frequency bands will be in Backhaul, effectively the data-pipe between the base-station and the core network simultaneously serving the data needs of all network users.

www.electronicsworld.co.uk Although mmWave and E-band
(71GHz to 86GHz) have delivered major leaps forward with data rates in excess of 10Gbps, it is what comes next that is now capturing people’s attention and creating the biggest challenges. Te next target bands that are attracting
considerable attention for telecoms aiming to breach the 100 GHz mark are the W and D-Bands. Te W-band, which spans 92-114 GHz, and the D-band, covering 130-174.8 GHz, represent substantial opportunities for advancing telecom infrastructure. Tese bands are pivotal as they are expected to see the first commercial deployments above 100 GHz, marking a significant milestone in the journey towards ultra- high-frequency communications. In terms of development, the W-band is currently at an advanced stage with
