Why PCF-1
- Industry-leading Df of 0.0001 minimizes signal attenuation over long transmission paths
- Lowest Dk in the PCF series — ideal where maximum signal propagation speed is required
- Highest mechanical strength (13 MPa) in the product line, improving handling and downstream lamination yield
- Advanced multi-stage fabrication (multi-dimensional powder blending, fibrillation, and void-elimination processing) ensures uniform ceramic dispersion and consistent electrical performance across the sheet
Recommended Applications: 5G mmWave base station antennas, satellite VSAT terminals, automotive radar (77 GHz), phased-array RF modules
