ECEN 2420 - Wireless Electronics for Communication

Catalog Data ECEN 2420 (3). Wireless Electronics for Communication. Explores fundamental principles behind the operation of a radio, including a practical introduction to circuit elements. The course covers the components and operation of a radio (transmitter and receiver) with simple signals. Students learn through demos the practical basic properties of all needed components with an introduction to principles of operation.
Credits and Design 3 credit hours. Selected elective course.
Prerequisite(s) PHYS 1120, Physics 2
APPM 1360, Calculus 2 for Engineers (or MATH 2300)
Corequisite(s) None.
Instructor(s) Zoya Popovic.
Textbook David Rutledge, The Electronics of Radio, Cambridge University Press, 1999, ISBN 0-521-64645-6 paperback.
Course Objectives For students to:
  1. Be aware of possible careers in RF engineering and a microwave/RF track they can follow within the curriculum and to know more about the general widespread area of wireless communications.
  2. Have acquired basic electrical engineering skills, such as reading schematics, use breadboards, solder printed circuit boards, read data sheets, and recognize standard components.
  3. To have the experience and confidence to be able to understand, build, troubleshoot, and operate a whole electronic system such as a radio transceiver.
Learning Outcomes After taking this course students will be able to recognize and use the following concepts, ideas, and/or tools:
  1. Basic analog circuit analysis, including Ohm's, Kirchoff's and Joule's laws in time and phasor domains.
  2. Basic radio frequency (RF) principles, such as propagation of radio waves, characterization of coaxial cables, and properties of oscillators, mixers, filters, amplifiers, and antennas.
  3. Characteristic properties from DC to MHz frequencies of basic analog components, such as resistors, capacitors, inductors, magnetic cores, semiconductors, and quartz crystals.
