SHF 일반 인터커넥트 케이블 General Interconnect Low Loss Cables

General Interconnect Low Loss Cables

General Interconnect SHF cable range defines all standard SHF cable electrical lines and performance. The range of cables covers the upper limit of the diameters for very low loss cables in this class. SHF cables are dedicated to all applications where minimal electrical loss is vital, as well as having a high level of phase stability in a broad temperature range.

Today SHF cables meet the highest performances in low loss
