Technical parameters of RF coaxial cables

SYV75-3, 5, 7, 9..., 75 ohms, polyethylene insulated solid coaxial cable. In recent years, some people have referred to it as a "video cable"

12-27

Structure and transmission characteristics of RF coaxial cables

The RF coaxial cable consists of four parts: an inner conductor, an insulator, an outer conductor, and a sheath. The insulator insulates the inner and outer conductors and keeps their axes aligned, which is called a coaxial cable.

Important parameters in RF cable testing

The quality of testing cables is crucial for testing applications, ensuring consistent and repeatable test results and maintaining long-term reliable electrical performance is particularly crucial.

01-14

Two factors to ensure the applicability of high-temperature wires

Cables can be installed in harsh environments and high ambient temperatures, but selecting the correct cable under the correct environmental conditions is crucial to ensure that the expected lifespan of the cable is not affected.

01-17

What is the difference between coaxial cable and twisted pair cable

The transmission characteristics of coaxial and twisted pair cables are specified by national standards and cannot be changed.

HHTAYZ-50-42 13/8 feeder performance

50 Ω spiral corrugated copper tube inner conductor foam polyethylene insulated annular corrugated copper tube outer conductor flame-retardant polyethylene sheathed coaxial RF cable (HHTAYZ-50-42) for wireless communication belongs to 50 Ω braided outer conductor coaxial RF cable for wireless communication under the category of communication and optical cable.

The concept of feeder standing wave ratio and its causes

In wireless communication, if the impedance between the antenna and the feeder does not match or the impedance between the antenna and the transmitter does not match, high-frequency energy will generate reflected waves in the antenna, and the reflected and incident waves will converge in the antenna feeder system to generate standing waves.
