IP3 means 3rd-order intermodulation products. When an amplifier is not perfectly linear it distorts the incoming waveform and if signals are input at two frequencies f1 and f2 the basic intermodulation products are at the two frequencies f1±f2.
3rd-order products are f1±2f2 and 2f1±f2. This gives problems because when f1 and f2 are almost equal, there are 3rd-order products that are close to them in frequency and therefore difficult to filter out.

What do you mean rf cable?
RF = Radio Frequency
What does a large Rf value mean?
it indicates that the pigments were adsorbed strongly
What is the advantage of RF over IR?
Because RF does not require line-of-sight.
Why rf choke is used in collpitts oscillator?
To isolate the bias circuitry of the transistor from the feedback network with RF currents.
How plasma is produced using RF generator?
It's power that is loss during the tuning of the RF network. Ideally the reflective power is tuned to zero before striking the plasma to maximize the efficiency of the RF generator.
