Directivity And VSWR Measurements: Understanding Return Loss Measurements
The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.
Ray-Optical Modeling Of Wireless Coverage Enhancement Using Engineered Electromagnetic Surfaces
In this paper, results are presented of propagation experiments conducted to verify the accuracy of a novel ray-optical scattering model for EES.
How To Test USB Power Delivery Over Type-C
USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.
Voltage Standing Wave Ratio (VSWR) Explained
Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.
