ECE 447 – Active Microwave Circuit Design

Spring 2025

Labs

Attendance to labs is required. The lab instructor should be informed of any conflicts one week ahead, in order to arrange an alternate time to complete the lab.

Lab Section:	ABA	ABB	ABC
Time:	Wednesday 1-3:50 PM	Wednesday 6-8:50 PM	Tuesday 6-8:50 PM
Location:	5076 ECEB	5076 ECEB	5076 ECEB

Lab Policy

Lab manuals will be posted on the course website.

Lab reports for the previous lab are due at the beginning of class.

All the lab reports should be printed out and handed to your lab TA.

Late lab reports will not be accepted, unless under exceptional circumstances approved by the instructor.

Background and Prelab of a lab manual contains relevant theory and background information of the experiment, which must be done before entering a new lab session.
