Rogers TMM4 PCB is a high-performance thermostat ceramic microwave laminate engineered for demanding RF and microwave applications. With a stable dielectric constant (εr) of 4.5 ± 0.045, TMM4 delivers exceptional signal integrity, low insertion loss, and outstanding thermal stability — making it the go-to material for aerospace, telecommunications, radar systems, and high-frequency circuit design.
Why Choose Rogers TMM4 Laminate?
TMM4 is part of Rogers Corporation’s trusted TMM series, a thermoset polymer composite reinforced with ceramic filler. Unlike standard PTFE-based laminates, TMM4 offers superior dimensional stability and is fully compatible with standard PCB fabrication processes — including drilling, plating, and soldering — without the handling challenges of soft PTFE materials.
Key Technical Specifications:
- Dielectric Constant (Dk): 4.5 ± 0.045
- Dissipation Factor (Df): 0.002 at 10 GHz
- Thermal Coefficient of Dk: -38 ppm/°C
- Coefficient of Thermal Expansion: 16–20 ppm/°C (x/y-axis)
- Thermal Conductivity: 0.70 W/m/K
Ideal Applications: Patch antennas, power amplifiers, satellite communication systems, military radar, and high-speed passive components.
