Circuit having isolated transmitting and receiving paths

Circuit having isolated transmitting and receiving paths

An electrical circuit includes an antenna connection for receiving a signal, a first signal path connected to the antenna connection, a filter arranged in the first signal path, and a first and a second gate circuit connected in series. The first gate circuit is connected to the antenna connection,...

description An electrical circuit includes an antenna connection for receiving a signal, a first signal path connected to the antenna connection, a filter arranged in the first signal path, and a first and a second gate circuit connected in series. The first gate circuit is connected to the antenna connection, and the second gate circuit is arranged between the first gate circuit and the filter. The first and second gate circuits each includes an impedance transformer arranged in the first signal path and a shunt circuit connected to ground. The shunt circuit includes a switch element and a capacitor. When the switch element is enabled, the shunt circuit defines a ground path through which at least part of the signal can pass to ground.
