Filter Networks

DLI provides the following standard types of component:

- Self Bias Networks are used to integrate source decoupling and user selectable bias resistance

- Bias Filter Networks which are designed to filter RF signals from bias and control lines from 10 MHz to 40 GHz

- RF Blocking Networks also known as E-Field Choke™

 

 DLI takes advantage of our high permittivity ceramics and combines it with thin film resistors to provide a device that integrates source decoupling and user selectable bias resistance. Custom Networks can be designed per your specifications. Please consult the factory for additional information or special requirements.
