Connectors are essential components in radio frequency (RF) systems, especially in high-frequency applications like Gigahertz (GHz) 5G devices. Designers have a broad range of connectors to choose from, but there are a few key parameters to consider when narrowing down the choices. Six keys to selecting and integrating GHz connectors include physical size, frequency range […]

Open RAN rewrites network-testing rules
Open radio access networks (Open RAN) bring new testing responsibilities that service providers haven’t had to contend with before. Learn why Open RAN changes the game for testing and validating network components, and how operators should approach these complex new requirements.
Efficient step-down dc-dc converter module delivers 72 W
Murata announced the development of the MYC0409, the industry’s highest power density (5.4kW/inch3), 48 Vin divide-by-4 charge pump capacitor divider module with all passive components integrated into a low profile PSiP package. Capable of delivering up to 72 watts of power with a peak efficiency of around 97-percent, the interleaved, switching capacitor architecture is based […]
Power consumption for IoT modules: Protocols matter
Time equals power when transmitting data to and from NB-IoT and LTE-M devices. How you use communication protocols can affect power use.
Chip varistor for automotive Ethernet sports strong ESD resistance
TDK Corporation expands its product lineup with a new chip varistor, type AVRH10C101KT4R7YA8, for automotive application Ethernet with strong resistance to ESD. Utilizing high-precision multilayer technology and optimizing the manufacturing process and process design, the product implements a tight tolerance of 4.7 ± 0.57 pF in the capacitance range and strong resistance to voltage ESD […]
Mixed-signal totem pole controller targets ultra-high density offline power supplies
onsemi introduced its latest mixed-signal controller dedicated to bridgeless totem-pole PFC (TP PFC) topology. The NCP1681targets ultra-high-density offline power supplies. Building upon the success of the NCP1680, which is suited for designs up to 350 W, the new controller extends the power capability into the kilowatt range. In the past, TP PFC designs required the use […]
How RedCap fits into 5G and IoT
Targeted at IoT applications, the reduced-capability in 5G will support a wide range of devices and applications that don’t need high speed, but do need low latency and high-reliability. 5G’s real promise comes not from mobile phones, but from industrial and business applications where network operators hope to recover the huge investments they’ve made in…
What are reflectionless filters? Part 4: Implementations
Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband which greatly improves performance of the RF signal chain. Filters are an area of intense interest, analysis, simulation, and often physical fabrication along with tests and academic papers. Yet, for hands-on design engineers, it’s important to be […]
What are reflectionless filters, Part 3: Basic principles
Standard filters reflect unwanted stopband energy, but reflectionless filters present a seamless impedance across both stopband and passband, which greatly improves performance of the RF signal chain. Beginning in 2011, Dr. Matthew A. Morgan of the National Radio Astronomy Observatory (NRAO) in Charlottesville, West Virginia, working with Tod A. Boyd and later with Wavley M. […]
Dual-channel low-side 4/5-A gate driver ICs handle fast MOSFET, WBG switches
Infineon Technologies AG has released the new EiceDRIVER 2EDN product family. Aiming at space-limited designs, the next-generation devices complement the existing 2EDN driver ICs by providing higher system-level efficiencies, excellent power density, and consistent system robustness with fewer external components. Building upon this expansion, the 2EDN family is now able to drive the power switch […]
