Claim:
1. A method for performing dynamic impedance matching, comprising: switching an impedance matching circuit of a communication apparatus to an operating band; applying a first number of tuning voltages to a first element of the impedance matching circuit and selecting one tuning voltage from the first number of tuning voltages as an operating voltage of the first element; and applying a second number of tuning voltages to a second element of the impedance matching circuit and selecting one tuning voltage from the second number of tuning voltages as an operating voltage of the second element, wherein the first number is different from the second number; wherein the first number is greater than the second number, and a sensitivity of the first element with respect to impedance matching is higher than a sensitivity of the second element with respect to impedance matching in the operating band.
