Practical RF Engineering
Follow a product from specification through design, verification, production, and field feedback.
From understanding to application
Put an idea to work.
Follow an explanation, make a prediction, then explore the calculation. These pairings connect Learn to the engineer’s workbench.
Connect frequency to physical size
Relate a signal’s repetition rate to its period and wavelength in a medium.
Understand an impedance mismatch
Follow a reflected wave, then compare reflection coefficient, VSWR, and return loss.
Understand receiver noise
See why stage order matters, then calculate the gain and noise figure of a cascade.
