Overview
Trans-Tech’s sub-assemblies take that complexity and make it simple. We select, machine, metallize, and test matched ferrite-dielectric assemblies in our own facility, delivering production-ready RF components that drop directly into your circulator, isolator, or filter design. The result is tighter spec compliance, better unit-to-unit consistency, and fewer surprises on your production line.
How Trans-Tech delivers
It starts with a conversation. Our applications engineers work with your design team to understand the electrical, mechanical, and environmental requirements of your system. From there, we:
Select and formulate materials from our materials, or we can help develop custom compositions if your application demands it.
Form and fire using our full in-house ceramics processing line: dry pressing, extrusion, isostatic pressing, tunnel and periodic kilns operating up to 1,700°C.
Machine to spec with CNC grinding, lapping, through-feed grinding, ID/OD slicing, and center-less grinding, holding tolerances that RF applications require.
Test everything before it ships. What arrives at your facility is ready.

Frequently Asked Questions
An RF sub-assembly is a pre-matched, pre-tested grouping of ceramic components — typically ferrite and dielectric elements — that drops into a larger RF device like a circulator, isolator, or filter. It eliminates the need for the system integrator to source, match, and assemble individual materials.
When you buy raw materials, you handle the machining, metallization, matching, and assembly. When you buy a sub-assembly from Trans-Tech, we help conceive, test, and provide production-ready components.
Yes. Our R&D chemistry lab can formulate new ceramic compositions, and our applications engineers work alongside your design team from concept through production qualification. We do this regularly for customers with requirements that don’t fit our standard material portfolio.
