RG402 is a type of coaxial cable commonly used in high-frequency applications, particularly in the realm of RF (Radio Frequency) and microwave communication systems. Here are some key characteristics of RG402 coaxial cable:

1. **Construction**: RG402 typically consists of a solid inner conductor surrounded by a dielectric insulator, which is further surrounded by a shield (usually made of braided or spiral-wound metal) and an outer insulating layer or jacket. This construction helps to maintain the integrity of the signal being transmitted by minimizing interference and signal loss.

2. **Impedance**: RG402 cables are designed to have a specific characteristic impedance, usually either 50 or 75 ohms. This impedance matching is crucial for efficient signal transmission and reception in high-frequency applications.

3. **Frequency Range**: RG402 cables are designed to operate effectively within a high-frequency range, often up to  18 GHz depending on the specific design and construction of the cable.

4. **Applications**: Due to its high-frequency capabilities and low loss characteristics, RG402 coaxial cable is commonly used in applications such as telecommunications, aerospace, military, test and measurement equipment, and other RF and microwave systems where reliable signal transmission is essential.

5. **Flexibility**: While RG402 cables offer excellent performance in terms of signal integrity, they may not be as flexible as some other coaxial cable types. This can be a consideration in applications where cable routing or installation involves tight bends or other physical constraints.

Overall, RG402 coaxial cable is a popular choice for high-frequency applications where signal integrity, impedance matching, and low loss are critical requirements.
