RA300L---Microwave substrate

RA300L---Microwave substrate Description:

RA300L high frequency circuit materials are ceramic- filled PTFE composites intended for use in commercial microwave and RF applications. This product was designed to offer exceptional electrical and mechanical stability at competitive price.
RA300L materials exhibit a coefficient of thermal expansion (CTE) in the X and Y axis of 8 ppm/℃, The Z-axis CTE is 20 ppm/ °C, which provides exceptional plated through-hole reliability, even in severe thermal environments.
RA300L laminates can be fabricated into printed circuit boards using standard PTFE circuit board processing techniques.RA300L laminates are frequently used in Automotive Radar ， Global PositioningSatellite Antennas, Cellular Telecommunications Systems—Power Amplifiers and Antennas, Patch Antenna for Wireless Communications, Direct Broadcast Satellites and Datalink on Cable Systems.
