Hello everyone,
Today, we will discuss the TLF-35 high frequency PCB.
Taconic TLF-35 is an advanced organic-ceramic laminate based on woven glass reinforcement. This material combines ceramic filler technology with coated PTFE fiberglass to deliver exceptional performance.
Key Benefits:
1.Enhanced Phase Intermodulation Distortion (PIMD):
TLF-35 is engineered to achieve improved PIMD performance, making it ideal for compact PCBs used in antenna applications. Its dielectric constant of 3.5 aligns with the required PIMD levels.
2.Superior Plated Through Hole (PTH) Quality:
This material demonstrates enhanced PTH quality, resulting in stable hole walls and insulation resistance, even for smaller drilled holes.
3.High Frequency Stability:
TLF-35 is designed to provide excellent performance at high frequencies, ensuring reliability in demanding applications.
4.Low Moisture Absorption:
With an ultra-low moisture absorption rate and low dissipation factor, TLF-35 minimizes phase shifts across frequencies, contributing to stable performance.
5.Cost-Effective Solutions:
This laminate offers a low-cost option for high-volume commercial microwave and radio frequency applications.
Typical Applications:
Antennas
Power Amplifiers (TD-SCDMA, WCDMA, LTE, WLAN, etc.)
Low Noise Amplifiers (LNA) and Repeater PAs
Passive RF Components (Filters, Couplers, etc.)
