Rogers Corporation RO3730 Antenna Grade Laminate
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE); Polytetrafluoroethylene (PTFE), Glass Filled, Molded
Material Notes:	RO3730™ Laminates have the excellent thermo-mechanical properties and electrical characteristics that antenna designers need. The laminates have a dielectric constant of 3.0 and a loss tangent of 0.0013 measured at 2.5 GHz. These values allow antenna designers to realize substantial gain values while minimizing signal loss. Materials are available with a demonstrated low PIM performance, with values better than -154 dBc (measured using Rogers' internal test method). Cladding is 1 ounce rolled annealed copper (35 microns thick). Features and Benefits: RO3730 reinforced woven fiber glass with optimized glass and filler loading - Improved mechanical rigidity, easier handling and processing versus non-reinforced PTFE products and lower dissipation factor Low PIM - reduced signal interference Loss - improved antenna gain Economically priced - volume manufacturing Environmentally friendly - Lead-free process compatible and RoHS compliant Typical Applications: Base station antennas RFID antennas WLAN antennas Satellite Radio antennas Information provided by Rogers Corporation.
