Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Using a headphone wire as an FM antenna The earliest portable AM/FM portable radios used two antennas: an internal long wire wound on a ferrite core for the lower-frequency AM band (550-1600 kHz), and a “whip” antenna […]

Getting one wire to do more, Part 3 – Powering the antenna LNA
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Providing DC power to an antenna amplifier via an RF coaxial cable In most applications where the antenna is located at a distance from the radio receiver front end, it is desirable or necessary to add a […]
Getting one wire to do more, Part 2 – Phantom power for the microphone
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. Powering microphones over the audio cable A classic engineering objective is to figure out a way to get one set of wires to provide a second function at little cost. This second part in the series looks […]
Simple double-duty: How to get one wire to do more, Part 1: The rationale
Using one wire in two very different roles is widely done, requiring some simple circuity and basic components. It makes a lot of sense to use an individual single copper cable and its connection between two points to do more than it initially intended, especially if that additional function is aligned with the primary function […]
How accelerator IO interface connectors and cables offer more options
Accelerator I/O connectors and cables provide secure, electrical contact and transmission for high-speed data. These devices typically make up one of the largest unit percentages of data-center equipment in terms of use and assembly. This is particularly true compared to top-of-rack (TOR) switching fabric network interface cables, such as Ethernet or InfiniBand. TOR switching is […]
How cable technology is evolving to meet high-performance networking
Persistent memory has become one key technology for the cloud as speed, efficiency, and volume at data centers advance. In high-performance computing, the cloud often requires data to be moved between multiple physical systems. Data may also be replicated for redundancy and protection, or it can be split across physical systems for performance. High-performance networking […]
Considerations for new datacenter, inside-the-box, twinaxial IO cables
New 50G, 100G, and 200G per lane internal copper twinaxial cable assembly solutions solve emerging DC/Cloud inside-the-box interconnect problems and new technology changes. Internal cable applications and high volume usages have also rapidly increased. For each new speed rate internal cable assembly product, design teams must closely review the detailed specifications for components, processes, and […]
Single-Pair Ethernet addresses industrial priorities, Part 2: Hardware realization
For applications driven by sensors more than high-speed data, the IEEE 802.3cg standard offers single-pair Ethernet connectivity with far lower cable costs and bulk. Part 1 looked at the context and standard which defines Single-Pair Ethernet and some of its variations, and how it fits into the IIoT application area. This part will look at […]
Single-Pair Ethernet addresses industrial priorities, Part 1: The IEEE 802.3cg Standard
For applications driven by sensors more than high-speed data, the IEEE 802.3cg standard offers single-pair Ethernet connectivity with far lower cable costs and bulk. Ethernet has come a very long way in adoption and speed from its humble inception driven in the early years by a team led by Robert Metcalfe at the Xerox Palo […]
10 important points to consider when using spring-loaded connectors (SLCs) in your design
By Marty Houlroyd Spring-loaded pins are rapidly finding new applications in modular product design. Also referred to as SLCs (spring-loaded connectors), this product resolves many of the manufacturing issues like misalignment, coplanarity, and tolerance stack up that can plague traditional pins and sockets. However, as flexible as SLCs are you need to be aware of […]
