METHOD AND SYSTEM FOR OPERATING A COMMUNICATIONS DEVICE THAT COMMUNICATES VIA INDUCTIVE COUPLING
First Claim
1. A method for operating a communications device that communicates via inductive coupling, the method comprising:
- detecting a system condition associated with the communications device; and
tuning a matching network of the communications device in response to the system condition, wherein the communications device comprises;
an analog transmitter driver;
an analog receiver;
an antenna;
a matching network controller; and
the matching network;
the matching network that including;
a hybrid transformer including a primary coil and a secondary coil, wherein the hybrid transformer separates the analog receiver of the communications device from analog transmitter driver of the communications device; and
an impedance unit connected to the hybrid transformer, wherein the impedance unit is adjustable in response to a system condition associated with the communications device; and
the matching network controller including a system condition detector configured to detect the system condition associated with the communications device and a matching network tuner configured to tune the matching network of the communications device in response to the system condition;
wherein the hybrid transformer has first, second, third, fourth, and fifth ports, the first and second ports being connected to opposite ends of the primary coil and connected to the analog transmitter driver, the third port being connected to a first end of the secondary coil and connected to the antenna, the fourth port being connected to a second end of the secondary coil and connected to the impedance unit, the fifth port being connected at a center tap of the second coil and connected to the analog receiver.
