Course Objectives

Hands-on course covering the theory and practice of microwave and wireless measurements. Topics include vector network analysis (S-parameters, calibration, TDR, material characterization, signal integrity), spectrum analysis (mixers, VCOs, PLLs, phase noise), noise figure, antenna gain and pattern measurements, communications measurements (modulation, BER, EVM, IQ constellations), and radar (FMCW, ISAR, RCS). Students complete six structured laboratory modules and an open-ended final project integrating these measurement techniques. Off-campus lab visits and demonstration sessions at industry facilities included.

Course Prerequisites

For EE 117B, prior enrollment in EE 117 or EE 142 is required and for EE 217B, prior enrollment in EE 210 is recommended. Students are expected to have a strong background in the following topics: Linear systems; Fourier Transforms; Transmission lines and Smith charts; Plane waves. No prior knowledge of integrated circuits is needed. The material in this class will be treated at a systems level, with a focus on measurement methods.

Syllabus

1. Vector Network Analyzers: VNA operation; architecture; calibration; time-domain methods; s-parameter measurements.
2. Spectrum Analyzers: SA operation; architectures; VCO/PLL measurements; mixers; non-linear measurements.
3. Noise: Noise theory; noise temperature and noise figure; jitter/phase noise.
4. Communications: AM/FM/PM modulation and demodulation; QAM; EVM.
5. Antennas: Antenna concepts; gain, radiation pattern, polarization measurements; mutual scattering; near-field methods.
6. Radar: Radar systems; FMCW radar; polarimetry; imaging.
7. Advanced RF Metrology: X parameters; spherical near-field measurements.

Labs

The labs (Cory 119) are reserved from 1:00-8:00 PM on Wednesdays and Fridays. Although this is the reserved time, each lab session could vary from 3 hours to 6 hours depending on the number of experiments being performed. Students will form groups of 3 to work through each lab. The groups must remain the same for the duration of the semester, including for the course project. The pre-lab submission for each week’s lab will be the notes from the lectures leading up to that lab session. The submission must be made before the start of the lab session. Each lab is accompanied by a set of questions, which the students must turn in as the lab report. A single lab report can be submitted per team.

The labs are mandatory and cannot be skipped without loss of grade. If you have a genuine time conflict due to travel/sickness, we can arrange for a make-up lab if you have received prior approval from the instructor. No exceptions will be made if prior approval was not received.

Course Project

Each team of 3 students will complete a final project. The scope of the projects is open ended so long as it includes RF measurement techniques covered in the class. Project proposal submission will take place at the end of the first month. The second month is dedicated to any revisions or CAD modeling. The last month is dedicated to the experiments related to the project, during which time there will be no scheduled lab sessions. There is a dedicated budget per project so students can buy the required supplies and equipment needed.

Textbook

No required textbook.
