Over the last decade, the complexity of RF component packaging has increased, driven by, for example, the integration of multiple semiconductor dies into compact, high-performance systems. This evolut...
This talk will highlight the advantages of additive manufacturing for the development of compact feed chains operating in the mm-wave regime. Both design and experimental aspects will be covered, offe...
With the advent of wearable sensors and Internet-of-Things (IoT), there is a new focus on electronics which can be bent so that they can be worn or mounted on non-planar objects. Due to large volume (...
This talk provides an overview of Delta-Sigma Modulation (DSM) for high-performance all-digital RF transmitters. After reviewing foundational concepts and key literature, we will describe advanced arc...
All-digital transmitters (ADTs) offer a digital replacement for conventional RF architectures, simplifying analog circuitry while enabling frequency agility, parallelism, and close integration with pr...
WMA-3: Advances in All-Digital RF Chains: From Delta-Sigma-Based Transmitters to PWM-Based Receivers
This talk discusses recent progress in all-digital RF architectures, considering the complete transmission-reception chain. On the transmitter side, advances in delta-sigma modulation are presented, e...
The transition to fully digital mobile communications is increasingly complex with 5G and even more with 6G. Since transmitters largely determine system efficiency, they face the toughest challenges. ...
RF/microwave filter design typically prioritizes high selectivity, sharp rejection, and flat in-band amplitude response. However, these features often cause large group-delay variations, which can sev...
Distributed MIMO (D-MIMO) is one of the most promising architectures for 6G wireless networks. Theoretical studies have demonstrated significant benefits of D-MIMO in terms of service uniformity, ener...
Low Earth Orbit constellation Satellite Communication (LEO-SATCOM) is one of the non-terrestrial networks, and the development of the Q/V band is urgently desired. The next-generation LEO constellatio...
