Abstract

A new view of diode power probes is presented is this paper. It is shown analytically, by simulations and with measurements, that calibration procedures for diode power probes should be rethought when measuring new wireless standard type of signals. In this respect, an improved analysis of long term-memory effects and the behavior of power probes when in the presence of wideband and high peak-to-average-power ratio (PAPR) signals is analyzed and studied. It is shown that a power probe calibrated with a single-tone sinusoidal excitation can provide erroneous values when used with modulated signals. This fact is ascribed to the low-frequency response imposed by the power probe baseband circuit. This hypothesis will first be theoretically demonstrated by use of a Volterra series, and then validated by simulations and measurements using a diode power probe. A similar approach is used for high PAPR signals when using multisines as the excitation signal.
