This shows the symbol of a circulator with . In the case of an ideal circulator, if a non-reflection termination is connected to each aperture other than the input, the input to aperture 1 will be transmitted only to aperture 2 without reflection or loss, and the input to aperture 2 will be transmitted only to aperture 3, and the input to aperture 3 will be transmitted to aperture 3. The input to is irreversibly transmitted only to aperture 1, and so on. Furthermore, as shown in Figure 2b, if an absorption resistor 4 is attached to one opening of a circulator with three openings, this is an isolator, and the signal input to opening 1 is transmitted to opening 2 with almost no attenuation. However, all the signals input to the aperture 2 are consumed in the circuit and do not appear at the aperture 1.

Through holes 11a and 11b with a diameter of about 1 mm are provided at the centers of YIGs 6a and 6b with a diameter of 13 mm. A similar through hole 11c is also made in the center of the conductor 7. A Teflon mandrel 12 is erected in the hole 11b of the YIG 6b, and the mandrel is passed through each through hole of the strip conductor 7 and the YIG 6a to overlap them. In this embodiment configured in this manner, alignment between the YIGs 6a and 6b and the conductor 7 is extremely easy and accurate, and variation in the distribution constant due to assembly is almost eliminated. Note that the hole provided in the center has almost no effect on the transmission characteristics because the hole is a small hole.
