Teledyne Lincoln Microwave’s design knowledge is built on decades of working with ferrite materials and a deep understanding of the interaction between an electromagnetic wave and magnetization within each ferrite type, contributing to optimum system performance.
Waveguide circulators and isolators have by far the best electrical characteristics and can be specified with insertion loss down to less than 0.2 dB in some cases. For microstrip and coaxial circulators and isolators, the insertion loss will typically rise to between 0.5 and 1.0 dB. Note that the wider the bandwidth, the poorer the insertion loss and isolation will be.
