ECE 4605 Radio Engineering (3C)

Wireless application circuit design for gain and filter control at radio frequencies to interface the baseband processing systems and the antennas of communiation systems. 4605: Design of radio transmitter and receiver circuits using scattering-parameter methods. Circuits include oscillators, radio frequency amplifiers and matching networks, mixers and detectors. 4606: Design of amplitude, frequency, and pulse-modulated communication systems, including modulators, detectors, and the effects of noise. Design basics and guidelines for phaselocked loops and several power amplifier configurations.

What is the reason for this course?

The first course provides a thorough coverage of fundamental communication circuits. these circuits are the building blocks of modern wireless communications systems.

Capstone Technical Elective for EE; Technical Elective for CPE. Typically offered: Fall. Program Area: Communications.

Prerequisites: C- or better in 2014, 3105, 3204 and 3614 for 4605.

Why are these prerequisites or corequisites required?

Pre: 2014, 3105, 3204 and 3614 for 4605. 2014 provides the student with the necessary background on engineering, communications, ethics and project management. Other necessary background consists of devices, biasing, and basic low frequency amplifier concepts (3204), basic transmission line, matching, and Smith chart principles (3105), and basic modulation concepts as covered in 3614.
