An optimal three-harmonic definition of class F at the intrinsic level is presented for realistic transistor models exhibiting IV characteristics with a nonzero knee voltage. This updated class-F definition is needed for use with the recently reporte

The measurement and modeling of the dynamic power dissipation of a dual-input Chireix power amplifier driven by LTE modulated signals is reported to optimize its dynamic efficiency. Two memory cubic spline FIR and NARMA behavioral models are verified

2017 IEEE Topical Conference on RF/Microwave Power Amplifiers for Radio and Wireless Applications (PAWR).
Waveform engineering is commonly used to optimize the power efficiency, linearity and output power of power amplifiers (PA). In this search for the optimal waveforms, PA designers have become interested in knowing the internal mode of operation of th

A testbed is reported for the measurement of the instantaneous power dissipation of a dual input Chireix power amplifier (PA) driven by an LTE signal. An FPGA system is used to dynamically control the phase difference and respective incident power le

Self-heating affects the RF performance of power transistors and must therefore be characterized for accurate device modeling. This paper presents an active loadpull (ALP) testbed which performs continuous wave measurements with the LSNA for arbitrar

Circuit-based large-signal device models remain extensively used to design integrated and hybrid microwave circuits. It has been recently demonstrated that device models can also be profitably applied under the form of a nonlinear embedding device mo
