​How much do you know about phase stable cable assemblies?

Phase-stable cable refers to a type of cable with high phase stability characteristics, and generally refers to cables in the microwave field. It is divided into high-temperature phase stability and mechanical phase stability, etc. The main characteristics are low loss and high transmission efficiency.

What is the mechanical behavior of phase stable cable assemblies?

The key mechanical properties of phase stable cable assemblies include volume, weight, minimum bending radius, compression resistance, and kink resistance. But the key to balancing the mechanical and electrical factors is to optimize the ratio between the connector interface and the diameter of the cable. Here are some commonly used connector/cable combinations:

1. Mini push-type connectors are most suitable for small diameter cables such as RG316;

2. SMA or N-type connectors are most suitable for cables between 0.10 and 0.30 inches;

3. The larger connector is most suitable for cables with a diameter of 0.30 inches.

Another important issue is cable retention and tensile resistance. The retention of a phase stable cable assemblies depend almost entirely on the thickness of the braid. Therefore, the retention force between the cable and the connector plug is directly related to the design of the ferrule, crimp sleeve and other associated devices.

The conductor wire type is also an issue. A solid core is often conducive to signal continuity, but the diameter and material can directly play a decisive role. Twisted wire is flexible, but it is more difficult to terminate.

In some applications, cable armoring is used to protect the cable from harsh environments and preliminary treatments such as excessive bending. Cables with thick protective sheaths/braided layers and strong insulating sheaths usually have a compression ratio of 80-100ppi, while the metal sheath can withstand up to 300ppi.

The compression resistance of solid insulated phase stable cable assemblies is the best, except in high-frequency conditions. Magnetically insulated cables have good high-frequency performance, but they are easily deformed.

Why is phase so important in the use of phase stable cable assemblies?

The phase stable cable assemblies need phase stability because:

1. Phase stability can achieve good phase tracking of the cable with temperature changes, while reducing residual errors and uncertainties.

2. Phase stability can improve the antenna gain, so that the cable can obtain better system performance and accuracy.

3. Phase stability can provide a better bit error rate (BER), thereby increasing the effective range.

4. Phase stability can extend the length of time between calibrations and minimize the drift between calibrations.

What is the function of phase stable cable assemblies?

Phase stable cable assemblies are mainly used in aerospace connectors and modern communication systems. For example, the low Loss phase stable cable can realize the impedance matching and energy transmission of the electric signal and microwave signal transmission path between the equipment or the equipment. Phase-stabilized cable assemblies play a huge role in the high-tech industry. Because it has many advantages, the biggest advantage is to ensure uninterrupted signal connection in an environment where severe impact and vibration, corrosive air, and strong thermal deviation are common.

Phase stable cable assemblies refer to a type of cable with high phase stability characteristics, which is favored by the market because of its low loss and high efficiency. LenoRF, as a Chinese pioneer in RF interconnects, can ensure the phase stable cable assemblies’ quality and the after-sales service.
