Handpicked technical articles and solutions
Isolators and circulators are non‑reciprocal devices based on ferrite materials, playing a critical role in RF systems by protecting key components (such as power amplifiers) and enabling directional signal transmission.
In this article, we look at how high-power, high-performance RF circulators and isolators work in real microwave systems, what “high power” actually means, how to interpret key specifications like insertion loss and isolation, and how to choose the right technology (waveguide, coaxial, drop-in, or microstrip) for your use case.
As 5G/6G, phased-array radar, and medical imaging advance, requirements skew toward broader bandwidth, miniaturization, and tighter consistency.
