Investigating the Electromagnetic Compatibility of Power Amplifiers in Telecommunications Equipment
Researchers at Amirkabir University of Technology have succeeded in conducting research that proves the significant impact of electromagnetic compatibility of power amplifiers in telecommunications equipment. According to the Public Relations Office of Amirkabir University of Technology, Hamed Daneshvar, a doctoral graduate of the university and the executor of the project "Modeling and Analysis of Electromagnetic Compatibility of Power Amplifier with Discrete Transistor in Shielded Enclosure with Aperture," stated that the power amplifier is one of the main components of any telecommunication equipment, adding: "The electromagnetic compatibility of this amplifier is a crucial issue in the performance of these devices."
He emphasized that previous research in this field did not simultaneously analyze the overall performance of the amplifier circuit under the influence of adjacent electric fields. In this research, the overall performance of the power amplifier circuit under the influence of an electric field in a shielded enclosure with an aperture was fully analyzed.
According to the researcher at Amirkabir University of Technology, for this research, a power amplifier with the desired specifications was first designed, and then this amplifier was placed inside a shielded enclosure with an aperture to reduce the effects of adjacent radiation fields.
He continued: "Furthermore, by subjecting this shielded enclosure to radiation, the electromagnetic compatibility of the power amplifier's performance was analyzed." The graduate of Amirkabir University of Technology stated: "Using the results and methods presented in this research, the electromagnetic compatibility of various telecommunications equipment such as mobile phones and communication satellites can be more accurately examined."
Daneshvar stated: "Two articles have been published based on the results of this research, with the main focus being on the analysis of electromagnetic compatibility of the amplifier using a time-domain finite difference numerical method."
He added: "To continue this research, by providing the transistor used in the design of the desired power amplifier and constructing this amplifier, the results of this research can be validated with measurement results."
Referring to the characteristics of this research, he said: "Higher accuracy in analyzing the electromagnetic compatibility of power amplifiers compared to other methods and software analyses, as well as reducing the electromagnetic susceptibility of power amplifiers used in various telecommunications equipment with the help of a shielded enclosure with an aperture, are features of this study."
It is worth mentioning that the project supervisors for this research were Dr. Ahad Tavakoli and Dr. Parisa Dehkhoda, who are faculty members of the Electrical Engineering Department at Amirkabir University of Technology.
