ABSTRACT:
Various embodiments of apparatus and systems are provided for electrically isolating two devices while transferring power and RF signals therebetween. An electrical isolation apparatus includes an isolation transformer that operates to transfer electrical power between first and second devices. The electrical isolation apparatus also includes a decoupling device that transfers radio frequency (RF) signals between the first and second devices. The isolation transformer and the opto-isolator cooperatively operate to electrically isolate the first device from the second device.
