Radio-frequency switch

摘要

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.
