High-Frequency Wireless Communications System: 2.45-GHz Front-End Circuit and System Integration

In this article, a course on high-frequency wireless communications systems is presented. With the 145-MHz baseband subsystem available from a prerequisite course, the present course emphasizes the design and implementation of the 2.45-GHz front-end subsystem as well as system integration issues. In this curriculum, the 2.45-GHz front-end subsystem includes only the antenna and the low-noise amplifier. Laboratory sessions are an essential part of the course. Successive completion of the laboratories automatically leads students to having a “working” 2.45-GHz wireless communications system. This course is beneficial to students who will pursue a career in wireless communication technology and related fields.
