Notch filter minimizes interference

WSN-00256 941 MHz pager interference notch filter from K&L Microwave Inc., part of Dover Corp.’s Microwave Products Group, mitigates signal interference caused by co-location of paging and cellular systems in buildings. Filter is highly selective with 45 dB minimum rejection from 940 to 943 MHz and is temperature stabilized from 0 to 50 °C. It reportedly maximizes performance trade-offs between sharp-shape factors and band-edge insertion losses. The company says its interference mitigation products achieve high performance by using quasi-elliptic responses coupled with high-ceramic resonators.
