Abstract
6G technology is set to revolutionize wireless communication, advancing far beyond speed enhancements to reshape how we interact with technology. A key
factor in this evolution is the efficient use of the radio spectrum, particularly in the centimetre-wave (FR3) bands, ranging from 7 GHz to 24 GHz. This thesis
investigates strategies for adapting FR2 transceivers to operate in FR3 frequencies through advanced tuning and wideband matching techniques. Additionally, it
presents the design of an antenna switch optimized for this frequency range.
The research leverages 22nm Fully Depleted Silicon On Insulator (FDSOI)
technology, incorporating both pre-layout and post-layout analyses to mitigate
parasitic effects and unwanted coupling.... (More)

Moreover, the antenna switch design demonstrated excellent performance, with an isolation of 37 dB and an insertion loss of 1.19 dB, making it suitable for high-frequency applications.
Future work will aim to refine the design further by enhancing bandwidth while
reducing the overall footprint. It will also explore additional circuit techniques to improve the matching network’s performance, as well as finalize the layout design and post-layout simulations for the antenna switch to meet precise performance specifications. (Less)
Popular Abstract
Imagine your smartphone or internet connection working faster than ever before,
with minimal delay and strong connectivity for all your smart devices. This is the
promise of the Frequency Range 3 (FR3) band, a key player in the future of 5G and
6G technology. Operating between 7GHz and 24GHz, FR3 can offer lightning-fast data speeds and incredible support for the Internet of Things (IOT), which includes
everything from smart home devices to autonomous vehicles. But there’s a catch,
while FR3 can deliver impressive performance, it also comes with challenges. The
high frequencies used in FR3 mean that signals can’t travel as far and struggle to
penetrate obstacles like walls. Additionally, setting up the infrastructure for FR3

Imagine your smartphone or internet connection working faster than ever before,
with minimal delay and strong connectivity for all your smart devices. This is the
promise of the Frequency Range 3 (FR3) band, a key player in the future of 5G and
6G technology. Operating between 7GHz and 24GHz, FR3 can offer lightning-fast data speeds and incredible support for the Internet of Things (IOT), which includes
everything from smart home devices to autonomous vehicles. But there’s a catch,
while FR3 can deliver impressive performance, it also comes with challenges. The
high frequencies used in FR3 mean that signals can’t travel as far and struggle to
penetrate obstacles like walls. Additionally, setting up the infrastructure for FR3
is costly. To make the most of this technology, we need to overcome these hurdles
with advanced technology, strategic planning, and supportive regulations.
One of the critical components in making this happen is the Radio Frequency
(RF) transceiver. Think of it as the communication hub of wireless technology,
capable of both sending and receiving signals. For FR3 to work effectively, we
need to fine- tune these transceivers so they operate seamlessly at the higher
frequencies of FR3. This involves adjusting their internal components to handle
the new frequency ranges and ensuring that the signals are strong and clear. This
achieved by a circuit called matching networks. Another essential part of this
setup is the antenna switch, which directs signals to the right path or antenna.
This helps ensure that communication remains clear and reliable.
During our work, we encountered challenges in making these networks perform perfectly. Parasitics (unwanted electrical effects) and coupling (interference
between components) made precise tuning difficult. Overcoming these issues required careful adjustment to ensure that the technology would work as intended
and deliver the fast, reliable connections we’re aiming for.
In summary, while the FR3 band holds great promise for the future of wireless
communication, turning that promise into reality requires overcoming technical
challenges. With continued innovation and careful planning, we can unlock its full
potential and pave the way for a new era of connectivity. (Less)
