WebFor the sake of scaling the graph, the IMD products (dBc) are actually 10 dB lower than the labels on the Y-axis. For instance, where tones are 100 MHz apart on the far left, IMD = -25 dBc, not 15 dBc. At this point in the sweep, usable linear power is still acceptable (around 47 dBm, or 50 W), however the left intermod IMD has WebJun 11, 2000 · This paper presents the improvement techniques of intermodulation-distortion asymmetries with wide carrier-spacing signals in L/S-band high power amplifiers.
