Rogers RO4535 High Frequency Printed Circuit Board RO4535 60mil 30mil 20mil Antenna PCB with Immersion Gold, Silver and Tin
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
General Description
RO4535 High Frequency Laminates, ceramic-filled, glass-reinforced hydrocarbon based material, are cost/performance materials from Rogers Corporation, specifically engineered and manufactured to meet the specific demands of the antenna markets. It has a dielectric constant of 3.44 and a loss tangent (Df) of 0.0037 measured at 10 GHz. These values allow antenna designers to realize substantial gain values while minimizing signal loss. Thus, it provides excellent passive intermodulation response required for mobile infrastructure microstrip antenna applications.
It is an affordable alternative to more conventional PTFE antenna technologies, thus allowing our designers to optimize the price and performance of the antennas. The resin systems of RO4535 dielectric materials are designed to provide the necessary properties for ideal antenna performance. The coefficients of thermal expansion (CTEs) in both the X and Y directions are similar to that of copper. The good CTE match reduces stresses in the printed circuit board antenna.
Features and Benefits
1. Low Loss 0.0037 , Low Dk 3.44, low PIM response: Wide range of application use
2. Thermoset resin system: Compatible with standard PCB fabrication
3. Excellent dimensional stability: Greater yield on larger panels sizes
4. Uniform mechanical properties: Maintains mechanical form during handling
5. High thermal conductivity: Improved power handling
Typical Applications:
1. Cellular infrastructure base station antennas
2. WiMAX antenna networks
