Pager Interference Notch Filter
K&L Microwave Inc. releases its model WSN-00256, a 941 MHz Pager Interference Notch Filter that mitigates signal interference caused by co-location of paging and cellular systems in buildings and businesses of all types. It minimizes this interference, enabling, for example, a clear channel through which healthcare providers can be contacted and called to duty. It is highly selective with 45 dB minimum rejection from 940 to 943 MHz and it is temperature stabilized from 0° C to +50° C. This filter maximizes performance trade-offs between sharp shape factors and band-edge insertion losses. The product uses quasi-elliptic responses coupled with high-Q ceramic resonators.
