Large- and Small-Signal IMD Behavior of Microwave Power Amplifiers
In this paper, large-signal intermodulation distortion (IMD) sweet spots in microwave power amplifiers are studied and predicted using a new mathematical basis. The variations in the IMD versus drive pattern with active bias point and the terminating matching networks are investigated. This nonlinear distortion model enabled the design of power amplifiers specially tailored to present a desired...
متن کاملIMD Performances of Harmonic Tuned Microwave Power Amplifiers
In this paper the linearity performances of harmonic tuned microwave power amplifiers is discussed and analysed, inferring some useful design guidelines. By a simplified active device model, the effects of the amplifier harmonic loads on the intermodulation distortion are investigated and experimentally validated showing the IMD3 performances of four hybrid amplifiers, designed using different ...
متن کاملPrediction of IMD in LDMOS Transistor Amplifiers Using a New Large-Signal Model
In this paper, the intermodulation distortion (IMD) behavior of LDMOS transistors is treated. First, an analysis is performed to explain measured IMD characteristics in different classes of operation. It is shown that the turn-on region plays an important role in explaining measured IMD behavior, which may also give a clue to the excellent linearity of LDMOS transistors. Thereafter, with this k...

متن کاملDesigning Highly-linear Microwave Power Amplifiers Based
This paper shows how intermodulation distortion, IMD, sweet spots can be used as a practically meaningful technology to design highly linear microwave power amplifiers. It starts by reviewing the physical origins of these points of large signal to nonlinear distortion ratio, distinguishing the ones uniquely determined by the active device’s quiescent point – small-signal IMD sweet spots – from ...
