High-Dk Ceramic-PTFE Microwave Circuit Board — Engineered for Precision RF Performance
Achieve superior signal integrity and compact circuit design with this 4-layer microwave PCB built on Rogers RT/duroid 6010.2LM — the industry’s most trusted ceramic-PTFE composite laminate for high-frequency applications. Manufactured to exacting standards at PCBSync, this board delivers the performance that radar, satellite, and antenna engineers demand.
Why RT/duroid 6010.2LM?
Rogers RT/duroid 6010.2LM is a ceramic-filled PTFE composite engineered specifically for electronic and microwave circuit applications requiring a high dielectric constant. With a Dk of 10.2 ± 0.25 at 10 GHz and an ultra-low dissipation factor of just 0.0023, this material enables meaningful circuit size reduction while maintaining exceptional signal fidelity at X-band frequencies and below.
The “LM” (Low Moisture) designation means this laminate absorbs only 0.01% moisture — virtually eliminating humidity-driven drift in electrical loss and dielectric performance. For engineers working on systems deployed in harsh or variable environments, this is a critical reliability advantage.

Immersion Gold Surface Finish
The ENIG (Electroless Nickel / Immersion Gold) finish on this board provides a flat, uniform solderable surface ideal for fine-pitch SMD components and wire bonding. It offers excellent shelf life, corrosion resistance, and consistent contact performance — essential for RF signal paths where surface roughness directly impacts insertion loss at microwave frequencies.
Designed for Miniaturization
A dielectric constant of 10.2 allows designers to significantly reduce microstrip line widths and overall circuit footprint compared to lower-Dk alternatives. Combined with the slim 0.8mm profile, this board is purpose-built for space-constrained applications where weight and form factor are as important as electrical performance — from airborne radar modules to compact satellite transponders.
The low Z-axis coefficient of thermal expansion ensures that plated through-hole vias remain mechanically reliable through repeated thermal cycling, making this 4-layer stackup a dependable choice for multilayer microwave assemblies.
