Product description

The LHS superflexible series cables provide the most flexible radio frequency cables at present, and have very good mechanical phase, low attenuation and attenuation stability, and high shielding. And has good processing capacity for power carrying. This is achieved through the cable structure, which uses low-density PTFE medium, silver-plated copper tape wrapping and intermediate layer shielding. This series of products are widely used in important occasions such as test and measurement, military antennas, base stations, and military electronic equipment;

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)


The temperature phase refers to the PPM value of the phase that changes with the cable in a certain temperature range under the static state. The PPM value of the LHS series cable in the temperature range of -50°~85°: about 950PPM, if PPM is converted into a percentage The number "%" is: 950ppm=0.95%, relatively speaking, the change is very small. The main reason is that the structure of the cable and the material of the dielectric layer play a decisive role. So this is also the characteristic of UHF series cables. In addition to the influence of temperature on phase In addition, the main factor that affects the phase change is the mechanical environment. The phase value of the cable and the amplitude of the phase change after bending are tested under the constant temperature and static state to determine the mechanical phase stability.
