ABSTRACT:
A radio frequency (RF) circulator includes a low temperature co-fired ceramic (LTCC) substrate and a ferrite structure disposed in the LTCC substrate. The circulator also includes first, second and third transmission lines disposed in the LTCC substrate and coupled between the ferrite disk and first, second and third ports of the circulator. The ferrite structure embedded in the LTCC substrate is exposed to an appropriate direct current (DC) magnetic field, to provide the circulator as an integrated LTCC substrate circulator.
