Product Description

Premium quality RF Splitter (4 Way, 50 Ohm, Low PIM) is used to divide a signal evenly between 4 output ports. It is weather-proof and can be used for indoor and outdoor installation. This is our premium signal booster custom model # 3 inventory item: RF Signal Splitter/ Divider/ Combiner (Four Way, 50 Ohm, Low PIM) with UPC 697691010588.

This signal splitter is compatible with any 50 Ohm cell phone booster and repeater including Uniden, Hiboost, SureCall and Wilson weBoost Electronics. It is typically used to connect several indoor antennas to a single booster. They are also often used to couple or "stack" four exterior antennas together to increase gain or shape signal coverage. Thus, it is also called, Signal Combiner, Consolidator, or Aggregator.

This wide band splitter operates on all cellular bands from 698MHz to 2700MHz. This design allows it to be used with many frequency bands making it useful for many applications including 900 MHz and 2.4 GHz WiFi and wireless video systems. The low PIM rated cavity splitter delivers low insertion loss and VSWR.

What does Low-PIM Splitter Mean?

To understand what Low PIM splitters mean, we must first understand what is PIM or Passive Intermodulation.

What is PIM and What Causes It?

PIM stands for Passive Intermodulation. In wireless infrastructure, PIM is measured in dB's and typically occurs when two or more signals are present in a passive, non-linear element or device, such as a DAS solution. PIM occurs when signals mix together in elements typically expected to operate in a linear manner, thus generating unwanted signals related to the original signals.

PIM has become a growing concern for cellular network operators, with problems occurring due to the ageing of existing equipment, when installing new equipment, or when co-locating new carriers. It’s of particular concern when duplexing new carriers into old antenna runs.

This intermodulation distortion occurs in components typically described as linear, such as antennas, connectors, and cables. However, these devices are capable of generating intermodulation signals at -80 dBm and even higher when exposed to high RF powers found in cellular systems.

For cellular operators trying to maximize the reliability, capacity, and data rate of their network, not to mention their return on investment, PIM is a very serious issue.

As the industry decides on the new "standard" RF connector, let us look at the difference between low PIM and high PIM.

  • Low PIM means happy customers and improved revenues for carriers, because users receive strong signals with more bandwidth.
  • High PIM means lost customers for the carrier, because the end-user receives limited bandwidth and poor cellular reception.

What Does This Mean?

It means that, from a hardware point-of-view, the design intention of every connection must be to minimize PIM and all connections must be tested to ensure correct installation. PIM testing is all-important to both design and installation processes to ensure top performance from the system. With today’s high-speed digital data communications, PIM testing has become critical. Because high transmitter power creates PIM, on-site testing should be carried out either at, or above, regular transmitter power levels to ensure PIM issues will be revealed.
