Course Goals

The goal of this course is to develop students' design, analysis, and evaluation skills at microwave frequencies where lumped elements (e.g., resistors, capacitors, inductors) are no longer appropriate. Through problem-solving and design activities, the course will introduce students to passive (85%) and active (15%) microwave devices, including filters, switches, mixers, couplers, power dividers, and diplexers, that constitute wireless communication systems between the antenna and the digital signal processor.

Any academic integrity violations will result in a FAIR report. Furthermore, the penalty will be as follows:

  • A score of 0 (zero) on the assignment or exam where the academic integrity violation occurred.

  • A second offense results in a grade of F for the course.

The following is a partial list of academic integrity violations for this course:

  • Copying homework or project reports from other students (working together and discussing is acceptable)

  • Copying homework or project reports from past solutions

  • Using websites such as Chegg or Course Hero while completing any course assignments or exams

  • Using unauthorized materials or discussing during exams

  • Communicating with any person during exams

  • Discussing the exam with any person within 24 hours of exam completion

  • Not an academic integrity violation: Distributing any course material without authorization. This includes uploading homeworks/solutions and exam solutions to websites, or sharing these documents with people not enrolled in the course.

    • Although not an academic integrity violation, it is a violation of the law and I will refer you to U.S. Attorney's Office for prosecution under The Digital Millennium Copyright Act.
