Pulse Electronics Corporation has introduced a new series of distributed antenna system (DAS) in-building ceiling mount multiple-input/multiple-output (MIMO) antennas. As Part of Pulse Electronics’ PIMinator™ line of low passive intermodulation (PIM) antennas, these antennas have high port-to-port isolation and superior gain patterns for both ports 1 and 2, providing wireless carriers with improved data throughput and implementation flexibility. They operate from 698 MHz through 5900 MHz, and have a PIM of -155 dBc which is one of the lowest PIM specifications on the market. There is minimal crosstalk between the ports and horizontally stable radiation patterns across all frequency bands. Through Pulse’s patent-pending innovation these antennas achieve -25 dB or better of inter-port isolation, preventing a reduction in signal-to-noise ratio and maintaining a high network data-rate throughput.
Often MIMO antennas have problems with non-circular gain patterns with high deviation from min-to-max gains. In MIMO or neutral host applications the wireless carrier may not have adequate performance on both ports. Pulse MIMO antennas lead the industry with a low 6 dB or less of peak gain differential. Low PIM improves DAS system performance because PIM reduces or degrades base station performance. Pulse Electronics’ extremely low PIM spec of -155 dBc at 2 x 20 watts (2 x 43 dBm) ensures high data rates to support streaming video for mobile devices. With low PIM there are fewer dropped calls, higher data rates, and fewer problems for cellular phone users and operators.
Pulse Electronics’ DAS MIMO antennas come in two configurations, the DASLTE500NFMIMO with an N-Female connector and a soon-to-be released Mini DIN version. The patent-pending PIMinator antennas are housed in aesthetically pleasing injection-molded radomes. They are RoHS compliant and PIM certified and come individually boxed or bulk packed.
