The upstream linear burst-mode transimpedance amplifier is the first to support 50 Gb/sec NRZ and 100 Gb/sec PAM4. They could drastically increase internet connection speeds and 5G infrastructure.
Single-port VNA covers frequencies to 14 GHz
The R140B from Copper Mountain Technologies lets you characterize antennas and cables without the need for an additional test cable.
ICs and software synchronize Open RAN networks
The Si55xx and Si540x timing ICs from Skyworks work in tandem with AccuTime software to provide low-jitter clocks and IEEE 1588 PTP fronthaul sync. In networks, timing is everything. Without solid, accurate timing and synchronization, data gets lost. Skyworks has introduced ICs that work with its software to address the timing relative to 5G radios…
RF power sensor covers 10 MHz to 8 GHz
The PWR-8PW-RC from Mini-Circuits let’s you measure peak, average, crest factor, and duty cycle. Anything you design with an RF transmitter needs power measurements to ensure it meets specifications. The PWR-8PW-RC Smart Power Sensor from Mini-Circuits connects to a PC, µC-based device, or network, letting you measure peak, average, crest factor, and duty cycle power…
Lens antennas focus multiple wireless beams
Using refraction instead of reflection or phased arrays, MatSing has created antennas that produce multiple beams. If you’ve recently attended a game at AT&T Stadium in Dallas, Allegiant Stadium in Las Vegas, Amalie Arena in Tampa, or even attended a presidential inaugural and used your phone, then you’ve probably used an antenna by MatSing. The…
Nordic IC adds Wi-Fi to IoT devices
Nordic Semiconductor’s nRF7002 accompanies the company’s Bluetooth devices by adding Wi-Fi 6 to low-power devices.
Can Wi-Fi 6E really share spectrum with incumbents?
Learn how Wi-Fi 6E standard-power transmitters must navigate around public safety and wireless backhaul signals in this video interview with Federated Wireless CTO Kurt Schaubach. For over two years, we’ve been hearing about how Wi-Fi 6E adds 1200 MHz of needed bandwidth to meet growing needs. The so-called “6 GHz band,” which covers 5.925 to…
High-speed data challenges physical-layer optics
Calibration is important in the measuring the effectiveness of fiber-optic cables. Fluke fellows Seymour Goldstein and Jeff Gust explain why.
Engineering at the heart of cellular repeaters
In a video interview with Nextivity CEO Michiel Lotter, EE World looks at the technology behind cellular repeaters that distribute signals over Ethernet cables before rebroadcasting.
Test service brings confidence to Wi-Fi devices, or finds bugs
Spirent’s Wi-Fi test service lets you run a battery of performance and precertification tests for routers, access points, or IoT devices. I recently replaced a failed old dehumidifier. Like so many devices, the new unit has connectivity, which is great because now I don’t have to go downstairs to check if the bucket is full.…
