• PIM chambers

    PIM (Passive Inter-Modulation) refers to RF signals at two or more frequencies in the same passive device, due to the nonlinear characteristics of passive device will produce relative operating frequency and some frequency components, and these frequency components are intermodulation products. If these useless frequency components are mixed with the operating frequency, when the frequency component is large enough, it will affect the normal communication. It is PIM caused by the non-linear characteristics of the passive components. Therefore, in the case of PIM inevitably, it needs to be tested to minimize the interference.
