PIM (Passive Inter-Modulation) Testing

The new AWS, UMTS, & LTE technologies are intended to be used for the transmission of high speed data transfer. To accomplish this with reliable proficiency, engineers have discovered that the quality of the entire RF system needs to be nearly perfect. It has always been understood that an RF signal can be dramatically affected by random distorted signals within the receive band of a RF system. 
These unwanted signals will show up as excessive frequency noise that can be within the bandwidth of a receive radio. This condition can cause degraded radio capacity and call failures. The condition is referred to as Passive Intermodulation Distortion (PIM).

The improvement of system component quality can reduce and eliminate this condition. PIM testing is designed to identify the existence of the unwanted signals that create RF interference. When the source of the unwanted signal is identified, corrective steps can be taken to eliminate the problem. This process requires an experienced testing professional that can correctly analyze the test data and recommend solutions to the problems that have been identified. TCE LLC is this experienced testing professional.
