F4BM255 High Frequency PCB Board

The F4BM255 is manufactured using a scientifically formulated and rigorously pressed glass cloth, prepreg, and PTFE (polytetrafluoroethylene) resin. Its electrical performance improves significantly over the F4B series, primarily through a wider dielectric constant range, lower dielectric loss tangent, increased resistance, and more stable performance. The F4BM series is a widely used and highly cost-effective product, and the F4BM255 is the most widely used member of the F4BM series.

Applications

Phase shifters, passive components, power splitters, couplers, combiners, feed networks, phased array antennas, satellite communications, base station antennas
