Course Structure: Lectures are organized so that the students can analyze and design the passive and active microwave circuits assigned for each lab project. The first two weeks cover basic transmission line theory and S-parameter analysis. The following eight weeks are divided into lab projects and a final project. Each project starts with analysis followed by simulations using CAD programs. Students must also fabricate the circuits and evaluate the performance.

1. Lab1 - Introduction to network analyzers
• One- and two-port calibration techniques
• Time- and frequency-domain analysis
• Unknown impedance measurements
2. Lab 2 - Matching circuit design by Designer
• Single- and double-stub matching circuit design using CAD
• Smith chart analysis
• Circuit optimization using Designer
3. Lab 3 - Quadrature hybrid design and fabrication
• Design of a 90-degree or 180-degree hybrid
• Circuit fabrication using a CAD program and copper tape
• S-parameter measurements using a network analyzer
4. Lab 4 - Low-pass filter design and fabrication
• Design of Butterworth, Chebysheb, Stepped impedance LPFs
• Circuit fabrication using a CAD program and copper tape
• S-parameter measurements using a network analyzer
5. Final Project: Amplifier design and fabrication
• Narrow-band amplifier design using Designer
• Circuit fabrication using a CAD program
• Gain measurements using a network analyzer
• Stability check and dynamic range measurements

ABET Student Outcome Coverage: This course addresses the following outcomes:

H = high relevance, M = medium relevance, L = low relevance to course.

(2) An ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors. (H) Students use microwave CAD software (Ansys ED) and modern microwave measurement systems (network analyzer, signal generators, spectrum analyzer). Similar equipment and software are widely used in industry. The instructor will discuss the professional ethics and responsibility in class.

(3) An ability to communicate effectively with a range of audiences. (H) Students must prepare extensive written project reports. Grades are given for writing quality as well as technical content of the reports.
