Enabling RF Circuit Techniques for 5G and beyond

Worldwide adoption of 5G mobile devices has been one of the main driving engines behind semiconductor industry. Since the initial release in 2020, 5G enabled devices surpassed the penetration of 3G/4G smartphones. 5G brings higher data capacity, low latency, and new applications. These are possible due to lower feature nodes such as FinFET 3nm/5nm but also due to improvements of the 5G RF front end modules. This paper presents 5G RF front end architectures with novel circuits and measurement details which will be part of future 5G+ mobile devices and beyond.
