Abstract
An apparatus for a network matching switch is provided. The apparatus includes a primary winding, a first secondary winding, a second secondary winding and a plurality of matching network paths. The primary winding is configured to generate a magnetic field based on an analog input signal. The first secondary winding is configured is inductively coupled to the primary winding. The second secondary winding is inductively coupled to the primary winding. The plurality of matching network paths are coupled to the first secondary winding and the second secondary winding. An active path is selected from the plurality of matching network paths and provides power to an active load.

An apparatus for a network matching switch, the apparatus comprising:
- a primary winding configured to generate a magnetic field based on an analog input signal;
- a first secondary winding inductively coupled to the primary winding;
- a second secondary winding inductively coupled to the primary winding, wherein the second secondary winding is distinct from the first secondary winding;
- a plurality of matching network paths coupled to the first secondary winding and the second secondary winding and associated with a plurality of output signals;
- and
- wherein an active path is selected from the plurality of matching network paths and provides power to an active load, wherein the active path is connected to one output winding of the first secondary winding and the second secondary winding and generates one of the plurality of output signals.
A method for operating a transformer radio frequency switch, the method comprising:
- generating a magnetic field based on an analog input signal by a primary winding;
- magnetically coupling a first secondary winding and a second secondary winding to the primary winding;
- selecting a path of a plurality of matching network paths as active based on matching characteristics for an active load, wherein the plurality of matching network paths are each connected to one of the first secondary winding and the second secondary winding and the selected active path is connected to the first secondary winding;
- and
- generating an output signal at the first secondary winding using the active path, wherein the selected path provides the matching characteristics.
