1. An apparatus comprising:
- an isolation transformer having;
a magnetic core;
first windings mounted on a first end of the magnetic core and communicatively coupled to a first device, the first windings receiving electrical power from the first device; and
second windings mounted on a second end of the magnetic core opposite the first end and communicatively coupled to a second device, the magnetic core operating to transfer the electrical power from the first windings to the second windings, the second windings outputting the electrical power; and
a decoupling device that transfers radio frequency (RF) signals between the first device and the second device;
the isolation transformer and the decoupling device cooperatively operating to electrically isolate the second device from the first device.

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.
