We present a fully automated on-wafer RF measurement platform that combines nano-robotics with AI-assisted computer vision to achieve sub-micron probe alignment and high repeatability. The system leve...
This paper presents a two-stage Doherty power amplifier (DPA) module designed for high-efficiency operation in 5G massive-MIMO base transceiver systems (BTSs). The DPA’s high performance is achieved t...
Chiral phonons are collective lattice vibrations with rotational atomic motion. Recently, chiral systems have been excited with coherent light sources to achieve magnetism and micro-degree Faraday rot...
This work presents an analog pre-distortion (APD) linearizer that employs a piecewise linear shape to accurately approximate the nonlinear inverse characteristics of a power amplifier (PA). The APD am...
This module provides a comprehensive overview of digital phased array architecture for aperture-level simultaneous transmit and receive applications, addressing practical implementation challenges at ...
This paper presents a liquid-crystal (LC)-based reconfigurable intelligent surface (RIS) capable of full two-dimensional beamforming with a reduced number of DC bias channels. A biasing architecture i...
This paper presents a W-band frequency-modulated continuous wave (FMCW) radar transceiver designed for centimeter-level imaging applications. The transceiver features a self-calibrated Type-III all-di...
