As factory for RF Passive components, most of our customer always asked us offer the Low PIM passive components, such as Low PIM power splitter, Low pim power tapper, Low PIM directional coupler etc.

Why intermodulation is so important in wireless solutions? and how to improve it? Below are 3 tips.

1) Select the appropriate frequency point combination.  The channel point group without third-order intermodulation is selected to open the frequency distance so that the third-order intermodulation will not fall within the frequency point used.

(2) Automatic gain (power) control (APC) technology is adopted to reduce the transmitting power in real time to reduce the intermodulation level, so that it will not fall into the nonlinear region of active devices;

(3) Improve the selectivity of the front end of the receiver and suppress the interference signal;  Improve the linearity of the input stage of the receiver, improve the intermodulation resistance ratio;  Improve the selectivity of power amplifier;
