WebApr 7, 2024 · Passive intermodulation reduces the signal energy within the useful bandwidth, but increases many noises outside the effective bandwidth. At the RF transmit port, the ACLR is generally used as an index of nonlinear distortion which is defined as the ratio of average power of adjacent frequency channel to that of transmit frequency … WebVolt-ampere nonlinearity is the origin of passive intermodulation, which means electric field-magnetic field nonlinear behavior of device or structure. Although DC nonlinear measurement is easier, it is not applicable to microwave frequency bands. This paper proposes a method to calculate the non-linear parameters of passive …

WebJul 23, 2024 · Passive intermodulation (PIM) is a pernicious and destructive phenomenon for cellular network operators. PIM shows up as a set of unwanted signals created by mixing two or more strong RF signals. Mixing generally produces the sum and difference frequencies of the two transmit signals F1 and F2. These signals are F1 + F2 and F1 – F2.
