Abstract:
A system for coupling a load to a communications device, comprising:a signal sensing module having at least a first, second, and third port; an impedance matching module that is automatically reconfigured to match a load whose impedance changes over time, said impedance matching module having at least a first, second, and third port; and an impedance matching control module having at least a first and second port, said impedance matching control module comprising means for receiving at least one input signal from said signal sensing module indicative of an impedance mismatch between said load and said communications device, a memory and a table that enable generation of at least one control signal proportional to said at least one input signal, means for generating said at least one control signal, an amplifier, wherein said amplifier receives said at least one control signal and generates at least one amplified control signal, and means for communicating said at least one control signal to said impedance matching module, wherein said first port of said signal sensing module is coupled to said communications device, said second port of said signal sensing module is coupled to said first port of said impedance matching module, said third port of said signal sensing module is coupled to said first port of said impedance matching control module, said second port of said impedance matching control module is coupled to said third port of said impedance matching module, and said second port of said impedance matching module is coupled to said load.
