Suitable for use with the company's PIMinator low passive intermodulation (PIM) indoor distributed antenna system (iDAS) family, Pulse Electronics introduces a new line of power splitters. The power splitters are designed to work with Pulse's PIMinator line of antennas in order to ensure a PIM spec of -155dBc at 2x20W.

When there are multiple antennas in a building, the signals need to be split between the antennas. Low PIM is the key to the performance of DAS systems because PIM reduces or degrades base station performance. With low PIM there are fewer dropped calls, higher data rates and fewer problems for cellular phone users and operators to deal with.

The line consists of four splitters: the DASSPLIT2WNF 2-way power splitter with N female connectors; the DASSPLIT3WNF 3-way power splitter with N female connectors; the DASSPLIT4WNF 4-way power splitter with N female connectors; and the DASSPLIT2WDIN 2-way power splitter with female 7 16 DIN connectors. The splitters have a dimension of 191.2x60.6x25mm (7.53x2.38x0.98"). They meet the demanding requirements of cellular operators and integrators of low PIM components for 2G, 3G and LTE/4G bands around the world. An iDAS allows users to receive cellular coverage inside a building instead of depending on a cell site outside the building.

Paul Fadlovich, Director of Infrastructure, Wireless Division, Pulse Electronics. comments: "The antenna is only as good as the splitter and vice versa. Most companies only make one part, the splitter or the antenna, but to get maximum performance, they need to work together. Pulse's PIMinator line of iDAS PIM antennas has an industry-leading PIM spec of -155dBc for both the antenna and the splitter, increasing capacity and data throughput and ensuring full performance of the antenna system."

Pulse Electronics' patent-pending PIMinator splitters are individually boxed. They are for use with Pulse Electronics' PIMinator line of low PIM iDAS ceiling mount omni antennas.
