Signal generator uses DDS to produce clean signals
The M9484C VXG signal generator from Keysight supports up to four independent channels for testing 5G and satellite receivers.
Hand-held spectrum analyzers come in 1.3 and 2.7-GHz versions
The Aim-TTi PSA Series 3 RF Spectrum Analyzers are available in 1.3 GHz and 2.7 GHz versions and have long battery lives with improvements over the previous Series 2 instruments, even rivalling more expensive handheld RF products. Improvements include a lower noise floor for increased sensitivity, a new frequency counter, additional RMS, Sample, and Average […]
Orchestration at the edge reduces network latency
Edge computing brings benefits to users by reducing network latency, thus improving services, but needs management orchestration. Here, we demonstrate how orchestration improves latency in an automotive edge-computing use case be reallocating network resources. Multi-access edge computing (MEC), commonly called “edge computing,” moves data processing to the edge of communication networks. Bringing computing close to…
Common-source dual GaN FET features 58 mΩ RDS(on), 20-A pulsed output current
EPC announces the introduction of the EPC2221, a common source dual gallium nitride FET rated at 100 V, 58 mΩ, and 20 A pulsed current. The EPC2221 can be used in lidar systems for robots, surveillance systems, drones, autonomous cars, and vacuum cleaners. The low inductance and capacitance of the EPC2221 allow fast switching (100 […]
GNSS core bundled with Wi-Fi, UHF and 4G LTE features
Septentrio announces the launch of AsteRx-U3, which is the successor of the popular AsteRx-U multi-frequency GNSS receiver for construction, mining, and other machine control applications. This new product combines Septentrio’s latest triple-band precise positioning GNSS core with extended wireless communication features including Wi-Fi, UHF, and 4G LTE. The versatile connectivity features of this receiver make […]
Battery backup chemistries for 5G small-cell sites
As the number of cell sites increase and their sizes decrease, engineers have options to consider for battery backup. Differing battery chemistries offer more choices and different performance levels. Selecting the right battery chemistry for each application is critical to ensure reliable, long lasting, and cost-effective power delivery.
How coherent optics increase data rates
Modulation and polarization multiply data capacity on optical networks. In the beginning of optical networks, all optical signals were based on a simple mechanism known as on-off keying (OOK). In simple terms, this mechanism works by switching a light on and off to transmit data. OOK is a wider definition for representing whether data is…
SP4T DC-6-GHz switch delivers high-power for RF applications
Menlo Micro has introduced a new single-pole/four-throw (SP4T) DC-to-6 GHz switch that provides best-in-class performance, reliability, and integration for 5G network infrastructure, test and measurement equipment, and other high-power RF switching applications. Built on Menlo Micro’s market-proven Ideal Switch technology, the MM5140 SP4T switch offers 25W power handling, ultra-low insertion loss, and the industry’s highest linearity, […]
GNSS receivers to get OSNMA functions
Septentrio announced the release of OSNMA functionality on their mosaic GNSS receiver modules. OSNMA (Open Service Navigation Message Authentication) offers end-to-end authentication on Galileo’s civilian signals, protecting receivers from GNSS spoofing attacks. Spoofing is a malicious form of radio interference, where faulty positioning information is sent to the receiver. For the last 2 years, Septentrio […]
