RF high speed interconnection is used in many electronic products where signal transmission quality is a critical factor in applications using high speed digital signals. An RF interconnect is the complete path that connects one device to another; RF-interconnect structures include coaxial cable assemblies, microstrip transmission lines, and waveguides with RF connectors, adapters, and attenuators. ..

Coaxial cable is the most commonly used transmission line for RF and microwave applications, because it provides reliable transmission with the benefits of wide bandwidth and low loss and high isolation. Major manufacturers of transmitting equipment, i.e. radio and TV, radar, GPS, emergency management systems, air and marine craft, use coaxial cables. The uses of ..

Electrical losses in a coaxial cable create heat in the outer and center conductors and are the two main types of coaxial cable loss, skin-effect loss and dielectric loss, respectively. This heat, or loss, can be calculated with the understanding of the following concepts. What is Skin Effect Loss? In coaxial cable, skin effect is ..

The coaxial cable provides a transmission line with low loss characteristics that can shield from outside signals and provide a durable yet flexible line that can be used in a variety of applications with a wide range of frequencies.  At microwave frequencies, much of the loss in coaxial cable transmission lines is characterized as metal ..

In the previous sections of the “Coaxial Cable Power Handling” blog series, a brief overview of coax power handling, and how cable size, cable type, signal frequency, and electron velocity through a cable, influenced the power handling capability of a coaxial cable. In this section, attenuation/loss, environmental factors, VSWR, and cable capacitance, will be touched ..

In the previous portion of the “Coaxial Cable Power Handling” blog series, we discussed an overview of coax power handling and how cable power handling impacts cable choice. In this portion of the blog series, we will take a deeper look into how cable size and type, as well as signal frequency and electron velocity ..

The coaxial cable provides a transmission line with low loss characteristics that can shield from outside signals and provide a durable yet flexible line that can be used in a variety of applications with a wide range of frequencies. Power handling capability, also known as the power capacity, is one of the important criteria in ..

Coaxial cable transfers radio frequency power from one point to another and, in the ideal world, the same amount of power would transfer along the cable to the remote end of the coax cable. However, real world conditions include some power loss along the length of the cable. Loss, or attenuation, is one of the ..

In the case of test and measurement, cable and connector installations, and coaxial assemblies, there is substantial design effort and thought dedicated to selecting the optimal coaxial cables and connectors for the project. These factors include electrical properties, mechanical properties, infrastructure logistics, pricing, environmental ratings, and standards and qualifications. However, there is more to a ..

The growth of wireless and high speed data applications has only expanded the use of coaxial cabling beyond traditional video and telecommunications uses. With the growth and standardization of coaxial cabling for a wide range of applications, coaxial cabling has become very familiar in the home, office, telecommunication facility, rail platform, industrial plant, and government/public ..
