Pulse Electronics unveils PIMinator MIMO DAS ceiling mount antennas

New distributed antenna system antennas offer Port 1 and Port 2 gain patterns and inter-port isolation

Pulse Electronics unveils PIMinator MIMO DAS ceiling mount antennas

Pulse Electronics Corporation, a provider of electronic components, introduces its new distributed antenna system (DAS) in-building ceiling mount multiple-input/multiple-output (MIMO) antennas.

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 698MHz through 5900 MHz, and at -155dBc have some of the lowest PIM specifications on the market.

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.

"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," explained Paul Fadlovich, director of infrastructure, Pulse Electronics Wireless Division.

"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."

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 43dBm) 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.
