IMS 2021: Components to test equipment
A hybrid International Microwave Symposium (IMS) took place live in Atlanta and online two weeks later in June 2021. See a selection of companies and product — mostly 5G — showcased in the virtual version.
Why voice over 5G relies heavily on LTE
Mobile phones are still phones. 5G devices need the ability to fall back to LTE when network support isn’t available. Here’s how and why.
Amplifiers drive mixers and multipliers
The AMM-7199 and AMM-7200 series from Marki Microwave drive downstream components in mmWave RF systems
Common-mode chokes optimized for high-speed interface noise suppression
Murata has released two automotive common mode choke coils intended for noise suppression in high-speed interfaces that use Serializer/Deserializer (SerDes) on Power Over Coax (PoC). Since this application requires a higher current compared to conventional differential interfaces, the DLW21SH391XQ2 and DLW21PH201XQ2 were developed specifically to handle a range from 300mA to 500mA. With sensor nodes becoming more compact, […]
Inside data centers: Cabling considerations for new FibreChannel links
A Fibre Channel (FC) storage area network (SAN) and Inter-Switch-Link (ISL) interfaces are an important part of modern data-center systems, including in hyperscale or enterprise ones. FC SAN is a high-speed network that connects servers and storage devices, and the Inter Switch-Link joins and maintains the traffic flow between switches and routers. A benefit to […]
Enterprise starter kit covers LoRaWAN device-to-cloud development
Digi International unveiled a new enterprise starter kit providing a complete LoRaWAN device-to-cloud solution, marking the company’s expansion into the low power wide area (LPWA) market. The turnkey starter kit offers a scalable, device-to-cloud onboarding experience that saves time, capital, and resources. The Digi solution helps enterprises meet their digital transformation needs with faster time to […]
Reed relays feature long life, rugged construction
Teledyne Relays announced the availability of four new reed relay product families, all offering extremely long life of up to 1 billion cycles, ideal for applications where high reliability is essential. The new product lines complement the already broad array of rugged switching solutions the company has been supplying for more than 60 years. Reed relays […]
VSWR and impedance, Part 5: Making a match
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The importance of impedance matching, minimizing reflections, and keeping a low VSWR means these topics have been studied extensively, ranging from analytical perspectives through many physical designs and implementations. This section looks at some matching techniques. […]
Q/V-band phased-array satellite antennas target next-generation satellites
A new phased-array user terminal is specifically designed for operation in the higher millimeter-wave (MMW) frequency bands for evolving next-generation communication satellites. The new low-profile antenna, based on ThinKom’s patented VICTS (Variable Inclination Continuous Transverse Stub) technology, will operate in the Q- and V-band frequencies (37.5-42.5 GHz and 47.2-51.4 GHz). These bands have been designated […]
