Abstract
A system for transferring electrical signals while providing electrical isolation may include a first circuit and a second circuit electrically isolated from the first circuit. The first circuit may provide a first electrical signal path for conveying a transmit electrical signal and including a first EHF communication unit. The first EHF communication unit may be configured to receive the transmit electrical signal and to electromagnetically transmit an electromagnetic EHF signal representative of the electrical signal. The second circuit may provide a second electrical signal path and including a second EHF communication unit. The second EHF communication unit may be configured to electromagnetically receive the transmitted electromagnetic EHF signal, extract a received electrical signal from the received electromagnetic EHF signal, and apply the received electrical signal to the second electrical signal path. A dielectric element may conduct the electromagnetic EHF signal between the first and second EHF communication units.
