Introduction of Phase stable cable

Phase stable cable is most often used in the military industry. For example phased array radar, missiles, ships, electronic countermeasures, etc. For example, phased array radar or missile equipment deployed in the plateau area, due to the great temperature difference between day and night on the plateau, will lead to temperature changes beyond the range of ordinary cables, resulting in large phase changes. The received signal will produce a certain time delay. Therefore, compared with other types of cables, phase-stabilized cables are superior in performance indicators and flexibility.

Phase stabilization is divided into mechanical phase stabilization and temperature stabilization. Phase stable cable whether mechanical phase stabilization or temperature stabilization, the smaller the phase change the better. First of all, there should be a measure.

The following is a list of catalogs：

• Mechanical phase stabilization: refers to the change of phase of coaxial cable during bending and vibration.

• The temperature stable phase refers to the change of phase of the coaxial cable during the temperature change.

Mechanical phase stable: It is the change of phase of coaxial cable during bending and vibration.

We assume that the standard is 18GHz, ± 3 ° / m, according to the national military standard requirements for testing the mechanical phase of the way, if it is higher than ± 3 ° then phase stable cable can not be called phase-stable cable. There is no standard for phase stability in China, there is no standard to talk about phase stability. Only uses a comparative method to measure the stability of the phase of each company's cable. It is said that the best any arc coaxial cable can do is ±2°/m@18GHz. In this application, as the owner said the phased array radar and array antenna are very widely used.

The temperature stable phase refers to the coaxial cable in the process of temperature variation, the phase change.

Temperature phase, currently the world best in temperature phase stability is gore coaxial cable. According to the national military standard temperature cycle experiment, do 10 cycles, the cable ends of the dielectric layer shrinkage within 2mm, the temperature range is -50 ° ~ 90 °, gore cable components change: <500ppm. Phase stable cable refers to a class of cables with high phase stability characteristics of a class of cables, generally referring specifically to the microwave field of cable. Divided into high-temperature phase stability and mechanical phase stability, etc., the main feature is low loss and high transmission efficiency. Phase stable cable" refers to low loss and high phase stable flexible microwave coaxial cable.

It is the responsibility of each manufacturer to produce a phase-stable cable that meets the standards, to ensure the safety of its supply and the healthy development of the phase-stable cable market. Zhenjiang LenoRF Industry co. LTD- LenoRF conducts many tests on phase stable cable for connection before they leave the factory, and the quality qualification rate is guaranteed.
