Abstract
A field device comprising: a device electronic; a bus interface embodied to connect the field device to a field bus and a surface acoustic wave connecting the device electronic to the bus interface is disclosed. The bus interface includes a bus driver transmitting communication signals corresponding to digital transmission signal provided by the device electronic onto the field bus and a bus receiver receiving communication signals from the bus and providing corresponding digital reception signals to the device electronic. The surface acoustic wave transceiver transmits the digital transmission signals provided by the device electronic to the bus driver and transmits the digital reception signals provided by the bus receiver to the device electronic. Thereby, the surface acoustic wave transceiver galvanically isolates the device electronic from the bus driver and the bus receiver.
