Broadband high power amplifier design using GaN HEMT technology
(IEEE, 2021)
This paper presents the design and measurements of a broadband GaN HEMT power amplifier intended for point-to-point radios, electronic warfare systems, and test and measurement applications. The proposed power amplifier ...
Visible light communication-based outdoor broadcasting
(IEEE, 2021-09-06)
In this paper, we explore visible light communication (VLC) as a wireless connectivity solution to enable outdoor broadcasting for public safety systems. Unlike indoor VLC broadcasting systems which build upon LED ceiling ...
