Custom Designed Filters

 

Euroquartz Filters specialises in the design and manufacture of custom electronic filters. Applications for such filters include defence, telecommunications and related applications. Each filter is designed and built to perform to customer specifications for electrical characteristics, reliability and resistance to hostile environments. Sample specifications, filter technical terms and design notes are available from this page.

Production Facilities

 

Production facilities are completely 'in house' and include computer-aided design using Euroquartz Filters' own analysis and synthesis software, crystal manufacture, precision coil winding, assembly, component and environmental measurements and performance analysis using level-measurement sets.

Small Batch Production - 'One Offs' or Batch Production

 

Our filter production process is geared to the manufacture of single units or small batches. The majority of products are assembled by hand to ensure the maximum flexibility and to avoid expensive and time-consuming tooling setup.

Low Costs

 

Euroquartz Filters' CAD programmes enable compact passive circuits to be designed using standard components wherever practicable. Many non-standard components are manufactured in-house to exacting specifications. We prefer to use skilled manual assembly rather than expensive automatic procedures for custom filter production, ensuring that small batch quantities of custom-built circuits can be produced to the highest quality standards at the lowest possible cost.

Fast Delivery

 

As all Euroquartz Filters' circuits and the majority of specialised components are manufactured in-house, there are no time-consuming delays due to dependence upon outside suppliers. As a result we pride ourselves in delivering orders 'on time, every time'.
