Radio-Frequency High Power Amplifier

Dear Colleagues,

RF power amplifiers are essential components in military or civil communication systems. For military use, it is used for high-power radio interference jammers or active electronically scanned array (AESA), and for civil use, it is used for 2G, 3G, and 4G transmitters of base stations and mobile terminals. In particular, in the case of civil use, it was mainly designed below 3 GHz in the past, but the operating frequency range is expanding to millimeter wave bands such as 28 GHz or 39 GHz, due to the recent commercialization of 5G communication. In addition, high-power RF power amplifiers are used to generate plasma in semiconductor processes. Recently, due to the development of semiconductor technology, CMOS, GaAs, and GaN-based solid state power amplifiers are actively being developed, but still, many studies have been conducted on vacuum tube-type power amplifiers for high output, depending on the application field. In this Special Issue, we invite researchers to submit their original research or review articles that are concerned with recent advances and applications in RF power amplifiers.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
