Abstract
A two-port isolator includes a metal case having an upper metal case portion and a lower metal case portion, a resin case integrated with the case, a permanent magnet member, a center electrode assembly including a ferrite member and center electrodes, and a laminated base. The intersection angle between the first and second center electrodes is adjusted to be different from about 90 degrees. The input admittance of an input port has a complex conjugate relationship with an external circuit. The intersection angle represents an angle at which the center lines of the outermost widths of the center electrodes intersect with each other. In other words, the intersection angle represents an angle of an end of the first center electrode with respect to the input port and an angle of an end of the second center electrode with respect to a ground port.
