Patent ID: 8587361

Claim:
An RF switch circuit for switching RF signals, the RF switch circuit comprising: a first terminal and a second terminal; a series connection of a plurality of transistors between the first terminal of the RF switch circuit and the second terminal of the RF switch circuit; and a control circuit configured to conductively couple, in a high impedance state of the RF switch circuit, the first terminal of the RF switch circuit to a control terminal of a first transistor in a series of the series connection of the plurality of transistors and the second terminal of the RF switch circuit to a control terminal of a last transistor in the series of the series connection of the plurality of transistors, the control terminal of the first transistor configured to control an impedance of the first transistor and the control terminal of the last transistor configured to control an impedance of the last transistor; wherein the first terminal of the RF switch circuit is coupled to a first terminal of the first transistor or is formed by the first terminal of the first transistor, such that, in the high impedance state of the RF switch circuit, the control terminal of the first transistor and the first terminal of the first transistor are shorted; and wherein the second terminal of the RF switch circuit is coupled to a second terminal of the last transistor or is formed by the second terminal of the last transistor, such that, in the high impedance state of the RF switch circuit, the control terminal of the last transistor and the second terminal of the last transistor are shorted.
