The availability of a new RF-10 ceramic filled PTFE PCB material for high frequency and microwave applications is being announced. RF-10 has been engineered to offer a unique combination of high dielectric constant, low loss, and excellent thermal stability.

A dielectric constant of 10.2 at 10GHz has been achieved with RF-10, allowing for significant size reduction of RF circuits and components. A dissipation factor of 0.0025 at 10GHz has been accomplished to ensure minimum loss for high frequency designs.

RF-10 has been formulated with an extremely low TCDK of -370ppm/°C for stable electrical performance over temperature. Isotropic X,Y,Z CTE values have been tailored to minimize board stress and prevent registration issues during fabrication.

A 2-layer process combining 1oz copper layers with a 0.254mm RF-10 core has been designed to provide the ideal stackup for controlled impedance transmission lines and components.

Key construction details are:

• 48mm x 35mm board dimensions have been standardized
• 6/8 mil trace/space has been demonstrated
• 0.3mm minimum hole size has been shown
• 1.4mil (1oz) copper layers are used
• Immersion gold finish is applied
• IPC Class 2 fabrication is performed

RF-10 has been identified as an excellent choice for:

• Microstrip patch antennas
• GPS antennas
• Passive RF components like filters and couplers
• Aerospace and satellite applications
