PolyPhaser Launches High Performance PIM Product Line

Friday, March 19, 2010

PolyPhaser, a member of the Protection Technology Group, announces the launch of the TSX Series of protection products during CTIA, March 23-25 in Las Vegas. This RF surge protector for broadband applications was engineered for high performance and low PIM (Passive Intermodulation) features for the carrier market.
The TSX Series offers significantly lower PIM – 155 dBC at a frequency range of 698 MHz to 2.7 GHz at -26dB return loss. It also provides DC pass and DC block options and is weatherproof with a bulkhead mount bidirectional broadband filter. The product offering covers the 700 MHz extended frequency band used in LTE. Its bidirectional capabilities provide strong support for both domestic and international applications.
“Through engineering innovation and collaboration with key carrier customers the TSX Series has met its goal in providing superior ultra low PIM capabilities enabling carriers to further optimize their networks”, said Vice President of Engineering Andrew Dawson.
What is PIM?
PIM distortion is typically caused by non-linear mixing of two or more frequencies in passive devices like cables and connectors. PIM signals are not desired due to their interference with signals in the receptive path. For optimal operation of RF systems, PIM needs to be kept to low levels in order to provide optimum network performance.
