Characteristic peak flatness
The peak flatness is the flatness of a peak-to-average ratio measurement for various
tone separations of an equal two-tone RF input. Figure 5 below refers to the relative
error in peak-to-average ratio measurements as the tone separation is varied.
The measurements were performed at –10 dBm and applicable for carrier frequency
≥ 300 MHz.
