What is a phase stable cable and what does it do

The most common applications for phase stablecables are in the military industry. For example: phased array radars, missiles, ships, electronic countermeasures, etc. For example, phased-array radar or missile equipment deployed in plateau areas, due to the extreme temperature difference between day and night on the plateau, can lead to temperature variations beyond the range of ordinary cables, resulting in large phase changes and a certain time delay in the received signal.

Therefore, compared to other types of cables, phase stable cables are superior in terms of performance indicators and flexibility.

                                  
Phase stabilisation, divided into mechanical phase stabilisation and temperature stabilisation
Mechanical phase stability: This refers to the change in phase of the coaxial cable during bending and vibration.
Temperature stable phase: refers to the change in phase of the coaxial cable during the temperature change.

                                   
Whether it is mechanically or temperature-stabilised phase, the smaller the phase change the better, and by how many degrees, there must first be a standard of measurement.

Assuming that the standard is 18GHz, ±3°/m, according to the national military standard requirements for testing mechanical phase, if higher than ±3° then the cable can not be called a stable phase cable, there is no standard on the stable phase in China, no standard to talk about the stable phase is actually no basis. Only by virtue of a comparative method to measure the stability of the phase of each company's cable. The best coaxial cable can achieve ±2°/m@18GHz, which is widely used in phased array radar and array antennas. zomwave can provide phase stable cable with ±2°/m@18GHz.

                                      
The world's best phase-stable cable is Gore coaxial cable, which has 10 cycles of temperature cycling according to the national military standard. ZOMWAVE is the leading manufacturer of RF cable assemblies in China, as Gore's equivalent supplier. It is a 100% replacement for gore in terms of performance, but at 30% of the price of Gore. Phase Stable Cables are cables with high phase stabilisation characteristics and are generally referred to as microwave cables. The main characteristics are low losses and high transmission efficiency. Phase stabilised cable" refers to a low loss, high phase stabilised, flexible microwave coaxial cable.

                                 
The cable is mainly used as a low loss, high phase stability flexible RF connection feeder in electronic equipment such as phase control radar and vector network analysers. Features: Microporous PTFE insulation, silver-plated copper foil wrapping with braided outer conductor, FEP sheath structure, low loss, high phase stability and high power electrical properties.
