Rogers TC350, a composite consisting of woven fiberglass reinforcement, ceramic filling, and a PTFE matrix, which is intended for use in the production of printed circuit boards. Rogers TC350 PCB has been designed to deliver enhanced heat - transfer performance due to its "Best - In - Class" thermal conductivity. Additionally, it aims to cut down dielectric loss and insertion loss. These lower losses ultimately contribute to higher amplifier and antenna gains and greater efficiencies. |

Features and Benefits: |
|
|
The elevated thermal conductivity of Rogers TC350 laminate allows for greater power handling capacity, reduces the occurrence of hot - spots, and enhances device dependability. Consequently, junction temperatures are lowered, and the life of active components is extended. These improvements are vital for enhancing the reliability of power amplifiers, increasing the MTBF, and reducing the expenses associated with warranties.
TC350 PCB offers excellent stability of the dielectric constant throughout a wide temperature span. This helps those designing power amplifiers and antennas to achieve maximum gain and minimize the wasted bandwidth due to changes in the dielectric constant as the operating temperature varies.
TC350 substrate has a strong adhesion to copper, using copper of microwave quality and low profile. As a result, the insertion loss is further reduced because the skin - effect losses of copper, which become more apparent at higher RF and microwave frequencies, are diminished. |
