  • Radio frequency multi-port switches
    Patent number: 9143184
    Abstract: A multiport radio frequency (RF) switch circuit is disclosed. The switch circuit includes a first transistor that is connected to a first port, a common antenna port, and a first enable line. The first transistor is selectively activatable in response to a first enable signal applied to the first enable line. There is also a second transistor connected to a second port, the common antenna port, and a second enable line. The second transistor is selectively activatable in response to a second enable signal applied to the second enable line. A first inductor connected to the first port and the second port compensates for parasitic capacitance between the first port and the second port from an inactive one of the transistors.
