Principles of Passive Intermodulation

Xiaolong Zhao received his B.E. degree in microelectronics and Ph.D. degree in electronics science and technology, Xi’an Jiaotong University, in 2012 and 2017, respectively. During his graduate studies, he participated in a national project and began to study the PIM effects in RF components. From September 2016 to December 2016, he studied as a visiting student at University of Michigan-Shanghai Jiao Tong University Joint Institute. From 2017 to 2018, he worked as an engineer engaged in signal distortion solution for the smartphone at Huawei Technology Co., Ltd. After that, he joined Xi’an Jiaotong University as an assistant professor. In 2022, he was promoted to an associate professor in the School of Microelectronics at Xi’an Jiaotong University. His research interests include nonlinear interference modeling and electromagnetic simulation for RF components and semiconductor-devices and systems for nuclear radiation detection.
