In choosing a way to mitigate electronic noise mitigation, it is necessary first to quantify it and ascertain its source. Thermal, also known as Nyquist or Johnson-Nyquist noise, is basis for many types of noise. It arises in all material objects to the extent that they are conductive. You can observe the effects of this […]

What is passive intermodulation?
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 […]
