From Prototype to Mass Production: Quickly available samples, scalable production—ideal for development cycles of any size
Thin Film Precision for High-Frequency Designs: Low insertion loss, high isolation, exact impedance control
Diverse Substrate Options: Al₂O₃, AlN, and other high-performance ceramics for various RF requirements
Flexible Metallization: Gold, copper, nickel, etc.—chemically or abrasively etched, plated or patterned for hybrid solutions
Design with Advantages: Fewer components, smaller PCBs, higher integration—ideal for compact RF modules

Split-dielectric designs, tantalum nitride thin films, custom filters? No problem—Johanson makes it happen.

Why Choosing the Right RF Substrate Is So Critical

Choosing the substrate material directly affects:

• Signal Quality (e.g., loss factors, Q factor)

• Thermal Stability (e.g., heat dissipation, temperature change behavior)

• Electrical Insulation and Mechanical Durability

• EMC Behavior and Coupling Effects in the RF Range

Johanson's portfolio includes:

• Lapped, polished, or as-fired ceramic substrates

• Substrates with or without metallization

• Finely structured circuits via chemical etching, laser structuring, or abrasive etching processes

Robust in Heat and Performance: Optimized Thermal Management

For high-performance RF components (e.g., PA modules, automotive radar, or space-grade designs), thermally resilient materials are a must. Johanson offers:

• Substrates with high thermal conductivity (e.g., AlN)

• Filled vias to dissipate local hotspots

• Substrates with properties matched to the CTE of the enclosure—ideal for hermetic packages or metallic heat sinks

Result: Less mechanical stress, longer lifespan, maximum performance in challenging RF environments.
