Rogers Corporation Soars With Advanced Materials at SATELLITE 2010

Rogers Advanced Circuit Materials (ACM) Division personnel will be on hand with full details on Rogers’ many microwave materials for satellite communications applications in broadcast, commercial, enterprise, military, and telecommunications markets. Materials on display will include RT/duroid® 5880LZ, RT/duroid 6202PR, and RO3003™ circuit-board laminates.

Visitors to the Rogers’ booth will learn how RT/duroid 5880LZ and RT/duroid 6202PR are ideally suited as circuit board materials for rugged airborne and space antennas and how RO3003 laminates provide the performance levels needed for the most demanding VSAT applications.

For example, RT/duroid 5880LZ, exhibits the extremely low dielectric constant (1.96) needed for low-loss circuits, but with the low z-axis coefficient of thermal expansion that is a prerequisite for reliable plated through holes (PTHs) in multilayer circuits. No matter how many circuit layers are involved in a design, RT/duroid 5880LZ is lightweight, making it the ideal circuit-board material for airborne and space-based systems.

For space-borne and satellite systems that depend on unyielding electrical and physical stability, Rogers RT/duroid 6202PR combines a low coefficient of thermal expansion with very low thermal coefficient of dielectric constant for consistent, dependable performance in the most hostile environments. RT/duroid 6202PR laminates are also engineered to deliver minimal variations in planar resistors even across large circuit boards to minimize the need for circuit tuning and help lower manufacturing costs.

For VSAT and other commercial satellite applications, including GPS antennas, Rogers RO3003 ceramic-filled PTFE composites support circuits at frequencies to 40 GHz. Available with a choice of three dielectric constants (3, 6.15, or 10.2), low-cost RO3003 materials maintain stable dielectric constant versus temperature and frequency with excellent dimensional stability in the X and Y directions. Their low dielectric losses translate into high-performance antennas and other high-frequency circuits for both satellite and ground-based applications.
