Abstract:
1. A circuit module comprising: a circuit board; and a first non-reciprocal circuit element and a second non-reciprocal circuit element each of which is mounted on the circuit board, generates magnetic flux in a direction parallel or substantially parallel to a principal surface of the circuit board, and does not have a yoke to reduce leakage of magnetic flux to an outside; wherein the first non-reciprocal circuit element and the second non-reciprocal circuit element are arranged to reduce magnetic coupling therebetween; and the first non-reciprocal circuit element and the second non-reciprocal circuit element are arranged such that the magnetic flux extending through the first non-reciprocal circuit element and the magnetic flux extending through the second non-reciprocal circuit element are perpendicular or substantially perpendicular to each other.
