Third-order intermodulation
Webpower and multiplies the output power of the nth-order products by 2 n. Thus, the asymp-totic slope of the fundamental is 1 dB/dB and the asymptotic slope of the nth-order prod-ucts is n dB/dB. The nth-order intercept point (IPn) is where the asymptotes for the nth-order intermodulation product and the fundamental cross. iIPn is the input power and WebOct 1, 2010 · Abstract and Figures. This paper presents the design of a circuit to generate 3rd- and 5th-order intermodulation (IM3 and IM5) products used for predistortion of base …

WebMar 11, 2024 · Abstract: The susceptibility of RF devices to the third order intermodulation $(IM_{3})$ is studied. In this paper, we propose an alternative of the classical two-tone test by using tones of not equal amplitude injected on RF devices. This new method aims at enhancing the intermodulation distortion characterization. WebJun 1, 2015 · Two-tone, third-order intermodulation distortion (IM) expresses the degree of non-linearity of an electronic device that has a definable dynamic range, such as an amplifier or mixer.

This value is then multiplied by 2 to yield 64 dB (the value of the third-order intermodulation products referenced to the power in a single tone). Therefore, the intermodulation products should be −64 dBc (dB below carrier frequency), or at an output power level of −60 dBm.
