Taconic RF-35TC High Frequency PCB With 10mil, 20mil, 30mil and 60mil Thick Coating Immersion Gold and Immersion Silver
(Note: PCBs are custom-made products; images and specifications are for reference only.)
Introduction
Welcome to our overview of the high-frequency PCB constructed with RF-35TC material.
RF-35TC is a PTFE-based, ceramic-filled fiberglass material from Taconic, specifically designed for high-frequency applications.
Key Advantages
Exceptional Thermal Management
This high-performance material provides superior heat dissipation, making it an ideal choice for thermally conductive, low-loss laminates. It excels in high-power applications by efficiently dissipating heat from both the transmission lines on the PCB and surface-mounted components like capacitors.
Furthermore, the dielectric constant (Dk) remains stable over a wide temperature range, enhancing antenna gains and efficiencies. The RF-35TC bonds effectively with low-profile copper, significantly reducing insertion loss.
Main Applications
1. Power Amplifiers: The extremely low dissipation factor (Df) of 0.0011, combined with high thermal conductivity, makes RF-35TC particularly suited for power amplifier applications.
2. Couplers: The low Z-axis coefficient of thermal expansion (CTE) and temperature-stable Dk are critical for both narrow and broadband overlay couplers.
3. Filters:The low X and Y CTE values are essential for maintaining precise distances between trace elements in printed filters:The low X and Y CTE values are essential for maintaining precise distances between trace elements in printed filters.
Additionally, RF-35TC is widely utilized in antennas, satellite equipment, and more.
