Non reciprocal components (i.e. circulators, phase shifters etc.) involved in satellite radar telecommunications at frequencies around 95 GHz are required to have particularly low losses for optimum performance. In this article the development of W, Y and M type hexagonal ferrite materials is described together with their magnetic performance away from ferromagnetic resonance, that is at low frequencies (1 GHz) as well as at the W-band (around 95 GHz). From the results, it appears that the M-structure is the most suitable material for the manufacturing of components for narrowband applications (IL <−1 dB at 94.5 GHz). The nature of the damping mechanism in the off-resonance cases is also discussed.
