Hello Everyone,
We are pleased to introduce our new high-frequency PCB, designed with RF-35TC from Taconic. RF-35TC is a high-performance material composed of a PTFE (Polytetrafluoroethylene) base, ceramic fillers, and fiberglass reinforcement. This combination ensures superior performance for high-frequency applications. |
|
|
|
|
|
First, let’s examine some of its standout benefits. |
|
|
|
|
|
|
|
|
Exceptional Thermal Management
RF-35TC excels in thermal management, offering superior heat dissipation performance. As a thermally conductive, low-loss laminate, it is ideally suited for high-power applications. Heat is efficiently dissipated away from both the transmission lines on the PCB and surface-mounted components, such as capacitors.
Additionally, RF-35TC maintains stable dielectric constant (Dk) across a broad temperature range, enhancing antenna gains and efficiencies. Its excellent bonding with low-profile copper further reduces insertion loss, making it a top choice for high-performance designs.
Key Applications
Let’s take a closer look at its primary applications:
1. Power Amplifiers: With an extremely low dissipation factor (Df) of 0.0011 and high thermal conductivity, RF-35TC is particularly well-suited for power amplifier applications.
2. Couplers: Its low Z-axis coefficient of thermal expansion (CTE) and temperature-stable Dk make it critical for both narrow and broadband overlay couplers.
3. Filters: The low X and Y-axis CTE values ensure precise maintenance of critical distances between trace elements in printed filters.
Beyond these, RF-35TC is also widely used in antennas, satellite equipment, and other high-frequency applications.
Now that we’ve explored the material’s advantages and applications, let’s dive into our PCB manufacturing capabilities. |
