An integrated circulator based on low-temperature cofired ceramics (LTCC) tapes and LTCC compatible ferrite tapes has been developed for the first time and its performance has been verified experimentally. The insertion loss is less than 2 dB and the isolation is better than 25 dB with a centre frequency of 7.45 GHz.

These results are in good agreement with simulations and offer a route towards integrated LTCC microwave circulators.
