Determining the appropriate Power Amplifier (PA) architecture for a given design specification can be a time-consuming task that could be better used designing the chosen architecture instead. Given t...
Load modulation has been a compelling technology for high-efficiency transmission of spectrally-efficient modulated signals. However, conventional architectures such as Doherty power amplifiers (PAs) ...
Together with both the development of device technologies and integration of analog and digital circuits, advanced power amplifier architectures have evolved to deal with ever-increasing system level ...
This presentation deals with the design of a Doherty PA Module (PAM) using 50V GaN technology in a 50Ohm in/out matched environment, including a bias controller IC. An overview of what is inside the P...
Our work will show a wideband reflectarray using TTD units on each element which can cover up to 2:1 bandwidth with excellent performance and scanning to ±60 degrees in all planes, and dual-pol operat...
In this presentation, mm-wave/sub-THz front-ends implemented by CMOS will be introduced for 6G communication, which includes 300GHz-band 4-element phased array transmitter, D-band 640Gbps MIMO transce...
Beyond the surge of connected traditional IoT devices, envision a new frontier: an IoT driven by living bioelectronic sensors, Cyber-Secure Biological Systems, designed to sense and wirelessly communi...
Wireless communication in the D-band inevitably needs beamforming to obtain a decent link budget. While fully digital beamforming yields too much overhead in power and area, analog beamforming, at lea...
In this talk we will address the application of innovative frequency generation techniques based on large integer frequency multiplication to RF front-ends for communication. These techniques allow th...
