How Rogers TC350 Plus Laminates Reduce Insertion Loss?
Rogers TC350 Plus laminates are designed to reduce insertion loss primarily through their low dielectric constant (Dk) and low loss tangent (Df). Here’s how these properties contribute to the reduction of insertion loss:
Low Dielectric Constant (Dk): The dielectric constant of a material determines the speed at which electrical signals propagate through it. Lower Dk values result in faster signal propagation, which reduces the time it takes for signals to travel from one point to another. This faster signal speed helps to minimize phase delays and reduce insertion loss.
Low Loss Tangent (Df): The loss tangent, also known as the dissipation factor, measures the amount of energy that is lost as heat when a signal passes through a material. A low loss tangent indicates that the material has low signal attenuation and minimal energy loss. In high-frequency applications, low Df values are crucial for maintaining signal integrity and reducing insertion loss caused by signal absorption.
By combining a low dielectric constant and a low loss tangent, Rogers TC350 Plus laminates provide excellent electrical performance at high frequencies. These properties help to minimize signal loss, maintain signal integrity, and reduce the overall insertion loss within the circuit.
