MIMO DAS antennas enable high multi-port performance

Operating from 698 through 5900MHz, the antennas are claimed to have some of the lowest PIM specifications on the market at -155dBc.

Competitor analysis shows that the Pulse DASLTE500NFMIMO has superior performance. 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 -25dB or better of inter-port isolation, preventing a reduction in signal-to-noise ratio and maintaining a high network data-rate throughput.

Low PIM improves DAS system performance because PIM reduces or degrades base station performance. Pulse Electronics' extremely low PIM spec of -155dBc at 2x20W (2x43dBm) 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.

Paul Fadlovich, Director of Infrastructure, Wireless Division, Pulse Electronics, commented: "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 6dB or less of peak gain differential. We've identified some competitors with as high as 16dB of peak gain differential in their model of low-PIM MIMO antennas."

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-moulded radomes. They are RoHS compliant and PIM certified and come individually boxed or bulk packed.
