This book covers basics of III-V group semiconductor materials and GaAs and GaN based High Electron Mobility Transistors (HEMTs) most suitable for microwave and mm wave power amplifiers required for present wireless communication systems and upcoming 4G and 5G mobile base stations. The book describes design and analysis of classical class of amplifier operations such as Class-A, B, AB, C and F. The coverage extends to advanced classes of amplifier operation such as extended continuous Class-B/Class-J, and extended continuous Class-F operations for broadband, high power and high efficiency performance. Analytical expressions are derived for circuit elements and performance parameters for clear understanding and required for practical design of power amplifiers. Each topic is supplemented with suitable schematic diagrams, analytical expressions and plotted results for clear understanding. 001451532 588__ $$aOnline resource; title from PDF title page (SpringerLink, viewed December 12, 2022). 001451532 650_0 $$aAmplifiers (Electronics) 001451532 650_0 $$aMicrowave communication systems. 001451532 650_0 $$aGallium nitride. 001451532 650_0 $$aSemiconductors. 001451532 655_0 $$aElectronic books. 001451532 77608 $$iPrint version: $$z9811962650$$z9789811962653$$w(OCoLC)1337855691 001451532 830_0 $$aLecture notes in electrical engineering ;$$vv. 955. 001451532 852__ $$bebk 001451532 85640 $$3Springer Nature$$uhttps://univsouthin.idm.oclc.org/login?url=https://link.springer.com/10.1007/978-981-19-6266-0$$zOnline Access$$91397441.1 001451532 909CO $$ooai:library.usi.edu:1451532$$pGLOBAL_SET 001451532 980__ $$aBIB 001451532 980__ $$aEBOOK 001451532 982__ $$aEbook 001451532 983__ $$aOnline 001451532 994__ $$a92$$bISE
