LCF series cables are UHF series economical radio frequency cables, which increase the cable attenuation with less floating and greatly reduce the cable cost. It is woven with low-density PTFE medium, aluminum foil longitudinally wrapped, and silver-plated wire. This series of products are widely used in electronic countermeasures, military electronic equipment, and other applications;
Attenuation vs. Frequency dB/100m
Power Handling vs. Frequency (Maximum）
Phase Stability (Detection method: one rotation along the repeated bending radius）
Amplitude Stability (Detection method: one rotation along the repeated bending radius）
Phase Change vs Temperature (PPM)
Features& Advantages
- Good amplitude stability
- Good price/performance ratio
- High shielding efficiency
- Maximum operating frequency DC-26.5GHz
