Abstract:
1. A radio frequency (RF) switch circuit with a first port, a first enable line, a second port, a second enable line, and a common antenna port, the switch circuit comprising: a first transistor connected to the first port, the common antenna port, and the first enable line, the first transistor being selectively activatable in response to a first enable signal applied to the first enable line; a second transistor connected to the second port, the common antenna port, and the second enable line, the second transistor being selectively activatable in response to a second enable signal applied to the second enable line; and a first inductor connected across the first port to the second port to compensate for parasitic capacitance between the first port and the second port from an inactive one of the first and second transistors.
