5G Large-Scale Antenna Arrays
The fifth generation of wireless communications is coming. 5G has the telecom world buzzing about the possibilities from greater speed and capacity to download or stream data, lower latency for improved responsiveness and potentially lower power consumption in both networks and handsets.
One of the main features of 5G communication is the use of large-scale antenna arrays to boost signal and capacity. It increases the network capacity and access rates of wireless base stations enabling networks to cope better with high-demand applications, while at the same time lowering transmission latency.
A leading wireless equipment manufacturer needed a power system for its latest antenna array system. It required high power density, efficiency and reliability for its radio frequency power amplifier. Artesyn’s ADH700 half-brick DC-DC power module, combined with the power of Artesyn’s ADQ500 quarter-brick DC-DC power supply to drive the system’s digital management unit, offered the perfect solution.
Both the ADH700 and ADQ500 power modules are integrated with a digital controller IC so offer remarkably higher power density, efficiency and reliability than older-generation units based on analog controller IC solutions. High efficiency is essential for a power converter in a 5G power amplifier application.
With an output of 700W at full load, the ADH700 power supply consumes less power than older-generation 700 watt units, which were typically full-brick size. For antenna and pole-mounted systems, size and mass are critical so this space-saving module was the ideal fit.
The ADQ500 series uploads its data to the system in real-time via a PMBus interface and can reset all parameters relating to the power supply to enhance fault protection, enabling the system to better control the power supply through smart management.
The stability and reliability of Artesyn’s standard power modules make them a popular choice for telecoms manufacturers and they have been used in telecom equipment in around one million 2G, 3G and 4G base stations. This particular customer was able to use standard modules from Artesyn’s extensive portfolio and create their 5G large-scale antenna array quickly and reliably.
Data Center Switching
A manufacturer of data center and telecom networking solutions has selected the Artesyn DS460S front end AC-DC power supply for its next generation series of 10 GbE switches. These switches are used by telecom carriers, financial services companies, government agencies, education institutions and a wide range of private enterprises in top-of-rack, end-of-row or other data center switching architectures. They can provide access layer switching in large data center networks, distribution or convergence layer services in large campus networks or core switching in medium and small networks.
The manufacturer will benefit from the high performing DS460S series which is rated at 460 watts and generates a main payload output of 12.3 Vdc and an auxiliary output of 12 Vdc for powering standby circuitry. It accepts a wide range 90–264Vac input and has a high typical conversion efficiency of 92% at 50% load. This high efficiency and reliability in a small package makes the DS460S series popular in rack-mounted server and networking switch applications.
4G Base Station
One of the world’s fastest growing telecom operators is using Artesyn’s AVD100 series of 100 to 120 Watt, 1/16th brick DC-DC converters on the embedded controller board inside its new 4G base station (BTS). This pioneering mobile network operator selected the Artesyn module due to its high density, excellent thermal performance and high efficiency (up to 92.5%). Since space was at a premium on the controller PCB, every component had to offer maximum value to the end application.
Laser Marking, Welding & Cutting
One of the world’s leading laser machine manufacturers has selected Artesyn’s LCM1500 series AC-DC power supply for its latest cutting machine, which will be used in the manufacture of metal parts for automobiles, small tools and other applications. The customer was looking for a cost-effective power supply but didn’t want to cut any corners in terms of reliability. This is the sweet spot for Artesyn’s LCM series single-output bulk front end power supplies. Backed by Artesyn’s legendary high quality and with a best-cost design and manufacturing process, the LCM series was definitely cut out for this kind of application.
Critically ill patients often require specialist medical equipment such as ventilators and patient monitors. A leading manufacturer of intensive care unit (ICU) equipment is using Artesyn’s LPS100-M series open frame AC-DC power supplies in its next generation patient monitor. The unit is designed for the specific sensitivities of patients with high needs and the LPS100-M series takes care of the monitor’s needs with a 100 watt medically-approved single output power source in a compact footprint at a competitive price.
