Abstract
Disclosed is a non-reciprocal circuit characterized in that the non-reciprocal circuit includes: a non-reciprocal circuit element having a magnetic substrate, a ground conductor, a central conductor, input and output terminals, a ground conductor, through holes, a permanent magnet, and a permanent magnet; and a dielectric substrate having input and output terminals, a ground conductor, a ground conductor removal portion, and solder connection portions, the ground conductor removal portion is disposed at a position at which the ground conductor removal portion faces the permanent magnet, on the dielectric substrate, and the permanent magnet has a thickness thinner than the heights of the solder connection portions.
Claims4
A non-reciprocal circuit comprising:
- a magnetic substrate having a first main surface and a second main surface opposite to the first main surface;
- a first ground conductor disposed on the first main surface of the magnetic substrate;
- a central conductor disposed on the second main surface of the magnetic substrate;
- multiple first input and output terminals electrically connected to the central conductor, on the second main surface of the magnetic substrate;
- a second ground conductor disposed on the second main surface of the magnetic substrate;
- a conductor connection portion to electrically connect the first ground conductor and the second ground conductor;
- a first permanent magnet disposed in such a way as to face the central conductor;
- a second permanent magnet disposed in such a way as to face the first permanent magnet across the magnetic substrate;
- a dielectric substrate having a third main surface and a fourth main surface opposite to the third main surface;
- multiple second input and output terminals disposed on the third main surface of the dielectric substrate;
- a third ground conductor disposed on the third main surface of the dielectric substrate;
- a ground conductor removal portion in which a part of the third ground conductor is removed;
- first metal connection portions disposed between the magnetic substrate and the dielectric substrate, to electrically connect the multiple first input and output terminals and the respective multiple second input and output terminals;
- and
- a second metal connection portion disposed between the magnetic substrate and the dielectric substrate, to electrically connect the second ground conductor and the third ground conductor, wherein
- the ground conductor removal portion is disposed at a position at which the ground conductor removal portion faces the second permanent magnet, on the dielectric substrate, and
- the second permanent magnet has a thickness thinner than a height of each of the first metal connection portions and a height of the second metal connection portion.
