Rogers TMM4 PCB 2-layer 50mil 1.27mm High Frequency Laminate

Rogers TMM4 PCB 2-layer 50mil 1.27mm High Frequency Laminate

Product Overview

The TMM4 PCB 50 mil is a high-frequency, high-reliability printed circuit board designed for demanding RF and microwave applications. Manufactured using Rogers TMM4 thermoset microwave material, this Rogers TMM Series PCB offers exceptional electrical performance, thermal stability, and mechanical durability. With a 2-layer rigid construction, immersion gold surface finish, and tight tolerances, this board is ideal for power amplifiers, satellite communications, antennas, and other high-frequency circuits.

Engineered for precision and signal integrity, this Rogers Immersion Gold PCB features a dielectric constant (Dk) of 4.50±0.045 and a low dissipation factor (Df) of 0.0020 at 10 GHz, ensuring minimal signal loss. The matched coefficient of thermal expansion (CTE) to copper enhances plated-through-hole (PTH) reliability, while the high decomposition temperature (425°C) ensures stability in harsh environments.
