A Rich History of Custom Integrated Assemblies

Mini-Circuits has a well established history of supporting customers in custom integration to achieve highly functional systems and sub-systems.

Leveraging our wealth of standard components, our application and systems engineers work directly with customers at the engineering level, up front and early in the development process following our method of design definition to provide both the customer and Mini-Circuits with a proven framework to define requirements accurately ensuring a successful development effort. The following examples illustrate the range of capabilities.
