  • Abstract
    Computer programs have been written for the design and optimisation of tracking stripline circulators, and used to predict the performance of broadband designs, 3.4-6.8 GHz and 18-40 GHz, using ferrites with 4 Ms=1230 G and 5000 G respectively. Initial results show promising agreement between predicted and experimental performance and an undesirable insertion-loss like spike has been identified as due to an inherent mismatch associated with circulator modes. The design and location of matching transformers are discussed, and the programs can be used with a commercial design software
