RADIO FREQUENCY SWITCH
First Claim
1. A radio frequency switch, comprising:
- a common port transmitting and receiving a radio frequency signal;
a first switching unit having a plurality of first switch elements connected in series and opening or closing a signal transfer path between a first port inputting and outputting the radio frequency signal and the common port; and
a second switching unit including a plurality of second switch elements connected in series and opening or closing a signal transfer path between a second port inputting and outputting the radio frequency signal and the common port,wherein the second switching unit further includes a first filter circuit unit connected to a control terminal of at least one second switch element of the plurality of second switch elements to remove at least one preset frequency band signal.

Abstract
A radio frequency switch may include a common port transmitting and receiving a radio frequency signal, a first switching unit including a plurality of first switch elements connected in series and opening or closing a signal transfer path between a first port inputting and outputting the radio frequency signal and the common port, and a second switching unit having a plurality of second switch elements connected in series and opening or closing a signal transfer path between a second port inputting and outputting the radio frequency signal and the common port. The second switching unit further includes a first filter circuit unit connected to a control terminal of at least one second switch element among the plurality of second switch elements to remove at least one preset frequency band signal.
