Open RAN networks pass the time
Network elements must meet certain frequency, phase, and time requirements to ensure proper end-to-end network operation. Synchronization architectures defined by the O-RAN alliance dictate how Open RAN equipment can meet these requirements. Open RAN continues to attract interest from service providers looking to reduce cost, improve competition, and drive technology innovation. The desire for a…
How timing propagates in a 5G network
5G’s high speeds place extreme demands on the components that maintain accurate time. Compliance with industry timing standards calls for accuracy in the face of temperature changes, shock, and vibration.
Look inside the 5G mmWave signal chain
Millimeter wave signals provide wider bandwidths and higher data rates than signals at lower frequencies. Take a look at the overall signal chain that falls between the antenna and the digital baseband. 5G new radio (5G NR) adds mmWave frequencies to cellular devices and networks. With that comes RF-to-baseband signal chains and components not needed…
Distributed feedback lasers power silicon photonic transceivers
Casela Technologies announced the introduction of its 1310nm band high-power, continuous-wave (CW) distributed feedback (DFB) lasers with record high power conversion efficiency and optical powers for silicon photonics-based transceivers. Digital transformation, 5G, a passive optical network (PON), and cable fiber initiatives continue to drive bandwidth growth for optical communications. East-west traffic inside data centers continues to…
Reference design platform cuts 4G/5G radio design time
The ADRV904x-RD reference design from Analog Devices includes an 8T/8R transceiver and covers from RF to optical.
Synchronizer keeps 5G networks on time
The Zyntai network time synchronizer from Net Insight picks up where precision-time servers leave off. Without timing and synchronization, networks would simply not run; data would never arrive at its destination. That’s where network timing products come in. At MWC 2023, Swedish network equipment vendor Net Insight will demonstrate Zyntai Time Node and Zyntai Director,…
Pole-mounted power supply provides -48 V for 5G
ABB Power Conversion introduced its SC1024 power system, which is designed for outdoor operation and well suited for private networking and broadband applications as well as small cell radios. The pole-mounted, enclosed power system features an integrated 1600W rectifier, and DC distribution, and offers 6 rack units of space for various 19” customer equipment to…
SP4T RF switches now available in production quantities
pSemi Corporation announces the production readiness of two new high-linearity switches targeted for the latest 5G wireless infrastructure and massive MIMO base station deployments. By using the new high linearity switches in hybrid architecture topologies, base station designers can save valuable board space and improve thermal management, reducing the overall system’s cost, weight, and power…
