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.

Webpower output, primarily when GaN amplifiers are used in multicarrier applications. The degree to which output power is affected is determined by tonal spacing and number of carriers. CPI has mapped this behavior using IMD sweeps and spectral regrowth charts. CPI has implemented this technology . on its newest GaNLink™ line WebFigure 5 shows the RFAL vs. Main 1 amplifier’s P out and IMD performance over the RFAL output power range from +26 dBm to +31 dBm.The fundamental power of the RFAL is … WebThis prevents false high SWR or exciter power readings, since cathode harmonics show as reflected power The tuned input circuit provides a stable low impedance to the cathode of the PA tube. This helps amplifier linearity and reduces IMD, and can improve PA efficiency prediction data mining techniques
