Abstract
Official abstract text for this publication.
A system that incorporates teachings of the present disclosure can include, for example, an apparatus having a matching network adapted to reduce a magnitude of a signal reflection at a port of the matching network. The matching network can have one or more controllable variable reactive elements. A controller can be adapted to determine reflection coefficient information from incident and reflected waves sampled at the port of the matching network, and follow at least one cycle of a coarse tune process for generating one or more control signals to tune one or more reactances of the one or more controllable variable reactive elements. Additional embodiments are disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a matching network that reduces a magnitude of a signal reflection at a port of the matching network responsive to one or more control signals supplied by a circuit, wherein the matching network comprises one or more variable reactive elements, and wherein the circuit determines reflection coefficient information from incident and reflected waves sampled at the port of the matching network, and initiates a tuning process by gene…
