STMicroelectronics’ STPOWER MDmesh M9 and DM9 N-channel super-junction multi-drain silicon power MOSFETs are ideal for switched-mode power supplies (SMPS) in applications from data-center servers and 5G infrastructure to flat-panel televisions. The first devices to be launched are the 650V STP65N045M9 and the 600V STP60N043DM9. Both have very low on-resistance (RDS(on)) per unit area, which maximizes power density and permits compact system dimensions. Each has the […]

What is “orthogonal”? (Part 1): mechanical design
The phrase and concept “orthogonal” is widely used in engineering, but it is also often misunderstood. I was chatting the other day with a non-technical friend and said something like, “Oh, that won’t happen. Those two things are orthogonal.” My friend looked at me and replied with a “huh?” and he was right to do […]
Omni outdoor antennas cover 5G low bands
Fairview Microwave Inc. has just released a new series of 5G outdoor-rated omnidirectional antennas that cover 4G, 5G, LTE, and CBRS bands. These small form factor omni antennas are the perfect solution when broad coverage is required but traditional base station antennas are too bulky or expensive. They support 6, 7, 8, and 10 dBi…
Small dual-band antenna for IoT optimized for 868 MHz and 915 MHz
Antenova Ltd launches a new low-profile antenna displaying strong performance on both Europe’s 868 MHz bands and the US 915 MHz bands. The new antenna is named ‘Lama’, part number SRFI065. It was developed for small connected devices operating on the LP-WAN networks including LoRa, Sigfox, Wi-SUN, and MIoTy. This antenna uses the ISM frequencies […]
Brooklyn 6G: Sustainability is the goal
NYU brought its wireless symposium back to life, now called Brooklyn 6G. This 2½ hour virtual symposium focused on sustainability as the most important topic in next-generation networks.
HD-BNC connectivity options for ultra-flexible low loss cable
Amphenol RF is pleased to announce the expansion of the HD-BNC product series with two new cable connectors. These connectors are specifically designed to terminate to the Times Microwave LMR-195-UF cable type which is engineered to be an ultra-flexible low loss cable option. The new configurations include a straight plug and bulkhead mount jack version […]
Wi-Fi 7 platform supports 320 MHz channel, 33 Gbps wireless interface capacity
The Wi-Fi 7-capable Networking Pro Series Gen 3 family of platforms is said to be the world’s highest performance Wi-Fi 7 network infrastructure platform portfolio commercially available. Building upon the multi-generation legacy of Networking Pro Series platforms, the products combine Wi-Fi 7 features with Qualcomm Technologies’ intelligent multi-channel management technologies to improve speeds, lower latency, […]

RIGOL’s new DSG3000B RF […]
Mitigate mmWave test costs in 5G smartphones
The economics of manufacturing test directly affect how you plan for the right number of test stations and test sites. Adding mmWave testing makes the difference.
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. When designing new and emerging technologies, you often need test equipment that’s a step ahead of the technology you’re developing. Given the complex OFDM modulations used in 5G radios, you need to accurately generate those signals…
