RF-30 High Frequency PCB 2-Layer Antenna Board with Immersion Tin Finish

1.Introduction of RF-30

RF-30 is an organic ceramic laminate that combines woven glass reinforced fluoropolymer chemistry with ceramic enhancements. Designed as the best value solution, it meets the low-cost, high-performance demands of microwave and radio frequency antenna applications.

The material's low dissipation factor, thermal stability and smooth surface profile minimize phase shift with frequency/temperature variations, delivering exceptionally low intermodulation performance. RF-30 is particularly suitable for large printed circuit base station antennas up to 102 inches.

With excellent peel strength for high-temperature assembly and power handling requirements, RF-30 maintains dimensional stability through its woven fabric design. The laminate meets UL-94V0 flammability standards.
