Integration of the ferrite devices in the RF front-end and active antennas is hindered by the need for external magnets, biasing 75 corvette door panels soft microwave ferrites.The hexaferrite-based self-biased nonreciprocal devices can operate without external magnets at mm-wave frequencies but the currently available hexaferrite materials inflict bang xxl switch duo high RF losses at lower frequencies, particularly in the wireless communication bands.In this paper, the parameters of La-Co-substituted hexaferrite compounds are used for the self-biased circulators in the low GHz frequency bands, and a means of the dissipation loss reduction are discussed.
