Abstract:
An apparatus includes first and second oscillator circuits. A transformer has a primary winding coupling the first oscillator circuit to the second oscillator circuit and a secondary winding. A first outgoing communications circuit is coupled to the second oscillator circuit and drives an amplitude modulated data signal thereto. A first incoming communications circuit is coupled to the primary winding of the transformer. A second outgoing communications circuit is coupled to the secondary winding drives an amplitude modulated data signal thereto. A second incoming communications circuit is coupled to the secondary winding. The secondary winding is magnetically coupled with the primary winding so the secondary winding receives an output power and an incoming data transmission based upon the amplitude modulated data signal, and so the primary winding receives an incoming high speed data transmission based upon the amplitude modulated data signal.
