Coaxial cable derives its name from the spatial relationship shared between the center conductor and the outer conductor. Figure 1 shows this "co-axial" positioning of conductors. A British engineer and mathematician by the name of Oliver Heaviside first patented the basic design of coaxial cable in 1880 (Patent Number:...

Product Brochure To assist customers who have a need to streamline their supply chain and logistics, Delta Electronics Manufacturing now offers a broad range of coaxial cable assemblies and other connector-related, value-added component subassemblies.

One thing that the test and measurement, sensors, radar and wireless markets all have in common is the need for robust, high performance microwave cable assemblies. A major attribute of such cables is electrical stability, which has been achieved through the development and advancement of cable technology over many...

In microwave systems coaxial microwave links often have to be regularly connected and disconnected, which means threading and unthreading, torquing and untorquing. As a result, it is not possible to densely pack regular connectors as room is needed for threading and for the use of a torque wrench. Also,...

With modern electronic warfare trending toward the use of portable electronic systems in the field of battle, the environmental sealing qualities of interconnects are under scrutiny now more than ever. Conditions ranging from driving rain to dust storms can wreak havoc on the performance and longevity of electronic components...

This application note covers power handling capability of coaxial cables. The matrix of average power over frequency provided for each example cable type is to be used as a guideline. Peak and average power There are two potential failure modes in cables used to transmit high peak power. One...

Individuals working in digital applications tend to prefer the Time Domain Reflectometer (TDR), while those involved in traditional RF applications consider the Vector Network Analyzer (VNA) to be a laboratory staple. The push for ever-faster data rates has fueled an analytical re-thinking of high-speed digital signaling. Contemporary wisdom views...

Electrical noise is created naturally by almost any type of device. In circuits that need to amplify and process very low level signals, noise can interfere with the desired signal, causing degraded or complete loss of reception. This is significant for any wireless receiver, often being the limiting factor...

Herley Industries Inc. announced that its Herley New England division in Woburn, MA has been awarded a contract valued at approximately $11.7 M from a major US Prime contractor. Herley New England will manufacture a number of multi-function integrated microwave assemblies (IMA) for a US Navy Electronic Attack Aircraft....

December 2009 saw the first commercial launch of LTE networks, with TeliaSonera the first service provider in the world to offer the service in Stockholm and Oslo. 2010 promises to see the commercial launch of several LTE networks, including large operators such as Verizon Wireless in the United States...
