||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.

For students to:
- 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.
- Have acquired basic electrical engineering skills, such as reading
schematics, use breadboards, solder printed circuit boards, read
data sheets, and recognize standard components.
- To have the experience and confidence to be able to understand,
build, troubleshoot, and operate a whole electronic system such as
a radio transceiver.
After taking this course students will be able to recognize and use
the following concepts, ideas, and/or tools:
- Basic analog circuit analysis, including
Ohm's, Kirchoff's and Joule's laws in time and phasor domains.
- Basic radio frequency (RF) principles,
such as propagation of radio waves, characterization of coaxial cables,
and properties of oscillators, mixers, filters, amplifiers, and
- Characteristic properties from DC to MHz
frequencies of basic analog components, such as resistors,
capacitors, inductors, magnetic cores, semiconductors, and quartz
- Introduction and vocabulary, superheterodyne radio block diagram
- Basic linear components for analog electronics: Resistors, capacitors,
- Basic nonlinear components for analog electronics: Sources, diodes,
- Energy storage (RC and RL)
- Introduction to phasors and impedance, resonant circuits
- Filters (low-pass and band-pass), Butterworth and Chebyshev basics,
quartz crystal filters, Q-factor
- Transistor switches, series and shunt
- Basic amplifiers: Common emitter/source, emitter/source follower,
differential amplifier, class-A power amplifier
- Mixers and frequency conversion
- Transmission lines and coaxial cable
- Antenna fundamentals, line-of-sight power budget, propagation and
ionosphere effects on radio communications
