GOALS:

The objectives of this course are to provide a foundational knowledge of microwave circuit design, including:

1.        an understanding of transmission lines, microstrip lines, and network theory,

2.        an applied understanding of matching networks using lumped and printed circuit components,

3.        the practical design of hybrids, couplers, and dividers,

4.        practical design of microwave amplifiers and oscillators combined with matching networks and bias circuitry.

 

PREREQUISITE:

EE468 and Electrical Engineering Standing.

 

TOPICS:

1.        Review

2.        Waveguides

3.        Impedance Matching

4.        Network Theory

5.        Power Divider, Coupler, and Hybrid Circuit Design

6.        Microwave Amplifier Design

7.        Microwave Transistor Oscillator

OUTCOMES:

The following competencies should be imparted to the students:

1. Understanding of transmission line analysis and network theory.

 

2. Understanding of matching network design using lumped parameters or printed microstrip or strip-lines.

 

3. Ability to design matching networks, power dividers, couplers and hybrids using printed microstrip or strip-lines.

 

4. Ability to design microwave amplifiers, matching networks, and DC-Bias networks.

 

5. Ability to design microwave oscillators.

 

6. Ability to apply commercial microwave circuit design Computer Aided-Design tools.

 

COMPUTER USAGE:

Students design, simulate, and analyze microwave circuit devices using Agilent’s Advanced Design System (ADS) throughout the course. They start out using standard transmission line analysis using ADS, then progress to microstrip and strip line circuit analysis for more accurate analysis of hybrids, couplers, power dividers, and microwave amplifiers. Some students will progress to using the ADS Momentum simulator, which performs a rigorous method of moment analysis of the microwave circuit devices.

 

DESIGN CONTENT:

A number of design tasks are assigned throughout the semester using ADS, as well a final design project. The design projects during the course of the semester are specific design tasks. This will include:

1.        The design of matching networks at given frequencies for a specified bandwidth using lumped circuit parameters, transmission lines, and then microstrip circuits,

2.        The design of hybrids, couplers, and power dividers for microstrip circuits,

3.        Design of microwave amplifiers for a given device, and for a specified frequency, gain, and bandwidth. The course also requires a term project which requires the design and analysis of a microwave circuit.

The students are given the choice of one of several projects or can choose one on their own. The students must design a microwave circuit to certain specifications, and provide an analysis. The project requires a formal written report and oral presentation at the end of the semester.
