MRF 01 - RF Boot Camp

The essentials of RF, without the intimidation. Frequency, power, impedance, transmission lines, and the instruments that measure them, presented as a fast working foundation for engineers and newcomers alike.

MRF 02 - Demystifying Phase Noise Measurements

Phase noise separates a good signal source from a great one. Learn what phase noise really is, why it matters in radar and communications, and how to measure it correctly the first time

MRF 03 - An Introduction to Radar Principles (New Version)

Radar is round-trip timing done seriously. A transmitter fires a pulse, a receiver waits for a whisper of it to come back, and everything else in the discipline exists to squeeze range, bearing, and velocity out of that faint echo. This course opens with Maxwell, Hertz, and Hulsmeyer, then the echo principle, the block diagram of a primary radar, and the PPI display. The quantitative core follows: deriving the radar range equation, walking the loss budget, and covering PRF, duty cycle, and dwell time. A tour of frequency bands from HF to W-band explains why weather, surveillance, and fire-control radar live where they do, before pulse, CW, and FMCW architectures tie it to real systems. The final chapters open the hardware: antennas, phased arrays, and monopulse, then transmitters, pulse compression, and the vacuum devices, klystrons, TWTs, and magnetrons, that still anchor high-power radar. For engineers, technicians, and students who want the principles under the acronyms.

MRF 05 - Real-Time Spectrum Analysis in Practice

The signals that matter most today are the ones a swept analyzer never sees. Frequency-hopping radios, radar chirps, drone links, and interference bursts live for microseconds, and a sweeping receiver looks at any one frequency for only a sliver of that time. A swept trace gives you a beautiful average of a signal that was never average. This course starts with that problem and builds the instrument that solves it: the real-time spectrum analyzer, from the RF front end through the ADC, the FFT engine, and the persistence and waterfall displays that turn gap-free capture into something your eye can read.
