This 2-layer RF PCB is constructed with Rogers TC600—a specialized composite of PTFE, thermally conductive ceramic fillers, and woven glass reinforcement. Engineered to deliver exceptional thermal conductivity (for heat management) and low dielectric loss (for signal integrity), it meets IPC-Class-2 standards and is ideal for power-dense, space-constrained applications like amplifiers, antennas, and avionics components.

Material Overview: Rogers TC600 Laminates
Rogers TC600 is a advanced composite laminate designed to address two critical challenges in high-frequency and power-dense circuits: thermal management and signal loss. By combining PTFE (for low dielectric loss) with thermally conductive ceramic fillers (for heat transfer) and woven glass reinforcement (for mechanical robustness), TC600 delivers "best-in-class" thermal conductivity while minimizing dielectric and insertion loss. This unique formulation enables PCB size reduction (via higher efficiency), improves power handling, reduces hotspots, and enhances long-term device reliability—making it a top choice for avionics, antennas, and power amplifiers.

Core Benefits
Enables Compact Design: Higher efficiency (from low loss) and thermal performance allow for smaller PCB footprints compared to lower-Dk substrates, ideal for space-constrained systems.
Superior Thermal Management: Best-in-class thermal conductivity (1.1 W/mK) reduces heat buildup, minimizes hotspots, and boosts power handling—extending component lifespan.
Low Signal Loss: Ultra-low dielectric loss (0.0017–0.0020) preserves signal integrity, leading to higher amplifier/antenna gains and efficiencies.
Stable Performance Across Temperatures: Consistent Dk (TCDk: -75 ppm/°C) and low CTE ensure reliability in extreme temperature ranges (-40°C to 140°C).
Reliable Component Integration: CTE closely matches active components, reducing stress on solder joints and improving long-term assembly reliability.
Easy Processing: Mechanical robustness (from woven glass reinforcement) simplifies manufacturing while maintaining dimensional stability.
Typical Applications
This PCB is optimized for high-power, high-frequency systems requiring thermal efficiency and signal integrity, including:
-Power Amplifiers, Filters, and Couplers
-Microwave Combiner and Power Divider Boards (Avionics Applications)
