Abstract
A radio-frequency switch may include: a common port; a first signal transfer unit; and a second signal transfer unit, wherein the first signal transfer unit includes a first switch unit that has a plurality of switch circuit units, each of the plurality of switch circuit units having switches connected to each other with one forward-biased and another reverse-biased and being connected to a control terminal of respective switches in the first signal transfer part, and the second signal transfer unit includes a second switch unit that has a plurality of switch circuit units, each of the plurality of switch circuit units having switches connected to each other with one forward-biased and another reverse-biased and being connected to a control terminal of respective switches in the second signal transfer part.
Claims22
A radio-frequency switch, comprising:
- a common port connected to an antenna so as to transmit and receive first and second radio-frequency signals;
- a first signal transfer unit connected between the common port and a first port that inputs and outputs the first radio-frequency signal, the first signal transfer unit including a plurality of switches connected to one another in series;
- and
- a second signal transfer unit connected between the common port and a second port that inputs and outputs the second radio-frequency signal, the second signal transfer unit including a plurality of switches connected to one another in series,
- wherein the first signal transfer unit includes a first switch unit that has a plurality of switch circuit units, each of the plurality of switch circuit units having switches connected to each other with one forward-biased and another reverse-biased and being connected to a control terminal of respective switches in the first signal transfer part, and
- the second signal transfer unit includes a second switch unit that has a plurality of switch circuit units, each of the plurality of switch circuit units having switches connected to each other with one forward-biased and another reverse-biased and being connected to a control terminal of respective switches in the second signal transfer part.
A radio-frequency switch, comprising:
- a first signal transfer unit including at least one switch and connecting or disconnecting a common port that transmits and receives a first radio-frequency signal and a first port that inputs and outputs the first radio-frequency signal;
- and
- a second signal transfer unit including at least one switch and connecting or disconnecting the common port that transmits and receives a second radio-frequency signal and a second port that inputs and outputs the second radio-frequency signal, wherein
- the first signal transfer unit includes at least two switches connected in parallel and in opposite directions to a control terminal of the at least one switch in the first signal transfer part, the at least two switches of the first transfer unit are connected between the control terminal of the at least one switch and a gate terminal for a first gate signal, and
- the second signal transfer unit includes at least two switches connected in parallel and in opposite directions to a control terminal of the at least one switch in the second signal transfer part.
