Abstract
A switchable coil includes a first coil including a first outer coil and a first inner coil, the first inner coil and the first outer coil forming a first crossing-region, a second coil including a second outer coil and a second inner coil, the second inner coil and the second outer coil forming a second crossing-region, and the second crossing-region being inside the first inner coil viewed in a first direction, and a switch connected to a region facing the second crossing-region in the second inner coil.
Claims20
A switchable coil comprising:
- a first coil including a first outer coil and a first inner coil, the first inner coil and the first outer coil forming a first crossing-region;
- a second coil including a second outer coil and a second inner coil, the second inner coil and the second outer coil forming a second crossing-region, and the second crossing-region being inside the first inner coil viewed in a first direction;
- and
- a switch connected to a region facing the second crossing-region in the second inner coil.
A switchable coil comprising:
- a first coil including a first outer coil and a first inner coil, the first outer coil including a first crossing end portion and a second crossing end portion, the first inner coil including a third crossing end portion and a fourth crossing end portion, and the third crossing end portion being connected to the first crossing end portion through a crossing segment;
- a second coil including a second outer coil and a second inner coil, the second outer coil and the second inner coil forming a crossing-region, and the crossing-region being provided inside the first inner coil viewed in a first direction;
- a first switch connected to a first region facing the crossing-region in the second inner coil;
- and
- a second switch connected to the second crossing end portion and the fourth crossing end portion.
A transmit circuit comprising:
- a mixer configured to perform up-conversion of a transmit signal based on a local oscillator (LO) signal;
- and
- a matching network connected to an output of the mixer, the matching network including at least one switchable coil, and the switchable coil including
- a first coil including a first outer coil and a first inner coil, the first outer coil and the first inner coil forming a first crossing-region,
- a second coil including a second outer coil and a second inner coil, the second outer coil and the second inner coil forming a second crossing-region, and the second crossing-region being inside the first inner coil viewed in a first direction, and
- a switch connected to a first region facing the second crossing-region in the second inner coil.
