Abstract:
In semiconductor switches, the isolation can be limited by the capacitive coupling between the switch input and the switch output. Ultra-high isolation can be achieved by adding a coupled transmission line to the semiconductor switch. The coupled transmission line introduces inductive coupling, which cancels at least a part of the capacitive coupling between the switch input and the switch output.

Claim (Index 9):
A method to improve signal isolation in a portable transceiver, the method comprising:\n receiving at a switching circuit a radio frequency input signal from an antenna, the switching circuit including a coupled transmission line having a first transmission line and a second transmission line, and first and second transistors electrically connected in series, the switching circuit having a common terminal in communication with the antenna, a first terminal in communication with a receiver through the first transmission line, and a second terminal in communication with a transmitter through the second transmission line; and switching the switching circuit to conduct the radio frequency input signal from the antenna to the receiver through the first transmission line and to disconnect the antenna from the transmitter.
