DLI’s engineers select from numerous filter topologies to solve your frequency management problem. We have expanded capability beyond band pass designs to include notch filters, low pass and high pass filters and band stop filters and other passive devices such as dividers and couplers. Designs are customized to your requirements to offer performance, size and repeatability.
Advantages utilizing DLI Filter Technology
Temperature Stability (-55°C to +125°C)
Primary ceramics utilized in DLI filter designs are CF (εr = 23) and CG (εr = 67). Both of these materials exhibit excellent temperature stability across a wide range of frequencies. Regardless of the filter operating frequency, guard band needs not be designed into the device to meet a demanding temperature requirement. CF and CG do not outgas, do not exhibit signs of aging and have been exposed to a mega-rad of total radiation dosage with no degradation in performance. The filters will perform the same from outer space to the desert. The graphs below demonstrate the extreme stability of DLI custom ceramic devices.
