High power amplifier imd

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 WebThe adjacent channel leakage ratio (ACLR) of any general purpose RF device, whether a mixer, amplifier, isolator, or other device, is frequently dominated by the 3rd-order intermodulation distortion (IM3) of the device. The relationship between the IM3 performance and the output intercept point (OIP3) parameter of the device can be derived.
