K&L Microwave launches 941 MHz pager interference notch filter

SALISBURY, Md., 26 Oct. 2006. K&L Microwave Inc., part of the Dover Corp. Microwave Products Group, released the WSN-00256 941 MHz pager interference notch filter, which mitigates signal interference from co-location of paging and cellular systems in buildings and businesses of all types.

"High-power, co-location paging systems operating near or around 941 MHz can easily interfere with each other," says Rafi Hershtig, vice president of advanced engineering and R and D for K&L Microwave. "The new 941 MHz notch filter minimizes this interference, enabling, for example, a clear channel through which health care providers can be contacted and called to duty."

This custom notch filter is highly selective with 45-decibel minimum rejection from 940 to 943 MHz and is temperature stabilized from 0 to 50 degrees Celsius. The 941 MHz notch filter maximizes performance tradeoffs between sharp-shape factors and band-edge insertion losses.

K&L Microwave's interference mitigation products push the performance envelope by using Quasi-Elliptic responses coupled with high-Q ceramic resonators. For more information contact K&L Microwave online at www.klmicrowave.com.
