In the world of microwave and RF (Radio Frequency) technology, the Rogers AD255C commercial microwave and RF laminate material stands out as a technological marvel. Combining the superior thermal properties of a fluoropolymer resin system with selected ceramic materials and fiberglass reinforcement, this composite material offers exceptional performance and reliability. With its low dielectric constant, low loss characteristics, and excellent passive intermodulation (PIM) characteristics, the AD255C is revolutionizing various industries, including cellular infrastructure, automotive telematics, and commercial satellite radio.
Properties and Specifications
The AD255C boasts a dielectric constant of 2.55, making it an ideal choice for applications requiring precise control of signal propagation. With a dissipation factor of 0.0013 at 10 GHz and 23°C with 50% relative humidity, this material ensures minimal signal loss and excellent power handling capabilities. Its tight tolerance ensures consistent performance, even in demanding environments.
The thermal coefficient of dielectric constant is a critical consideration for applications exposed to varying temperatures. The AD255C exhibits a thermal coefficient of dielectric constant of -110 ppm/°C over a range of 0°C to 100°C, providing stability and reliability across a wide temperature spectrum. Moreover, its coefficient of thermal expansion in the X, Y, and Z directions is measured at 34 ppm/°C, 26 ppm/°C, and 196 ppm/°C, respectively, over a range of -55°C to 288°C. This characteristic makes the AD255C resistant to thermal stress and ensures longevity in diverse operating conditions.
Passive Intermodulation (PIM) is a critical concern in high-frequency applications, as it can cause signal interference and degradation. The AD255C addresses this challenge effectively with its outstanding PIM characteristics. With a low PIM of -159/-163 dBc at 30mil/60mil thickness, as measured by reflected 43 dBm swept tones at 1900 MHz, this material ensures minimal interference and superior signal integrity.
