摘要： A method and an apparatus are provided for impedance matching using an analog circuit. The method comprises providing the analog circuit to substantially match a start impedance to an end impedance and tuning a performance parameter of an associated circuit using the analog circuit operating at a high power level. The analog circuit may transform the start impedance to the end impedance using a characteristic impedance in a range above the start impedance and the end impedance. By reconfiguring the analog circuit, the associated circuit may operate at one of a first, second, or higher order frequency bands. By using a matching transformation process, reconfigurable matching circuits for medium and/or high power applications may be provided by using available lower power reconfiguration elements. In the matching transformation process, the intermediate impedance at which the reconfiguration is performed is higher than the matching processes used for lower power reconfiguration elements. A relatively smaller and cheaper reconfiguration element having lower parasitics may be used.

摘要： The present invention provides a method and an apparatus for assessing a capability, for example, linearity of an amplifier, such as that of a power amplifier including a radio frequency amplifier. In one embodiment, the method comprises defining a first figure of merit for a power amplifier based on a loss of linearity relative to a predefined linearity requirement for the power amplifier and/or defining a second figure of merit based on the first figure of merit and dependent upon a minimum frequency within a predefined frequency band for the power amplifier, characterizing the linearity thereof. In this manner, using a test setup, for digital mobile communication networks deploying one or more higher order modulation schemes with complex wireless transmission that results in non-constant envelope signals, linearity of power amplifiers in transceivers, such as a mobile station or a base station, may be sufficiently described. Moreover, the two defined figures of merit may be used to compare different amplifiers for these higher modulation schemes, making possible a comparison of different amplifiers independent of their implementation technology or design structure.
