WebOct 8, 2024 · Third-order intermodulation distortion. Two-tone, third-order intermodulation (TOI) distortion is a common test for RF distortion measurements. When two or more signals are present in a non-linear system, they can interact and create additional … WebThird-order intermodulation distortion (IM3) for a fre-quency filter occurs when system nonlinearities allow two strong out-of-band interferers spaced from an in-band fre-quency ωo by Δω and 2Δω (as shown in Fig. 2), to generate an in-band component back at ωo, corrupting the desired compo-nent at ωo [6]. More quantitatively, an input ... WebIntermodulation distortion. ... To be able to select five channels without any third order intermodulation products being produced, it is necessary to have 12 regularly spaced (e.g., 25 kHz spaced) channels available.

WebThe most important linearity specification for direct conversion mixers is the 2nd order intercept point (IIP2) due to the 2nd order distortion product falling within the baseband output spectrum, and the LT5575 boasts 54.1dBm at 900MHz (60dBm at 1900MHz). The LT5575 also has high 3rd order linearity and a low noise figure of 12.8dB. WebIntermodulation distortion generally specifies the level of in-band nonharmonic distortion due to second and third order nonlinearity. The intermodulation (IM) product is a spur typically specified in response to two strong narrowband signals or tones at the input of the receiver (or nonlinear device).

WebNonlinearity can give rise to intermodulation distortions in surface acoustic wave (SAW) devices operating at high input power levels. To understand such undesired effects, a finite element method (FEM) simulation model in combination with a perturbation theory is … WebIntermodulation distortion products are of special interest in the RF area, and a major concern in the design of radio receivers. Third-order IMD products can mask out small signals in the presence of larger ones. Third order IMD is often specified in terms of the third order intercept point as shown in Figure 8.5.
