The BBox from TMYTEK lets you control a signal’s amplitude and phase under software control. Use it to test antennas, phones, small cells, and measure material properties when subjected to mmWave signals. Testing beamforming antennas, user equipment, small cells, and other items requires that you have a way to create a steered signal. Taiwan-based TMY…

5G moves into production, causes test issues
5G Technology World talks with Teradyne’s Jeorge Hutarte, who explains components and over-the-air production test of 5G components. 5G phones, base stations, IoT, and other devices have moved into production, but like everything else, 5G’s mmWave frequencies bring new challenges there, just as they have with design and deployment. For starters, production facilities don’t what…
DesignCon video: Compressible RF connectors
Like all technologies, 5G needs more that just the “glamor” components such as baseband ICs, RFICs, and phased-array antennas. Interconnects can make or break a design, and 5G is no exception. So, besides giving birth to active devices, 5G has also spawned a need for connectors. To that end, TE Connectivity has developed the ERFV…
DesignCon video: Why details cause project failure
“Twenty-five percent of projects reach market on time and on budget,” said Andrea Fox of Mentor Graphics to a gathering at DesignCon 2020. The rest need more time, more money, or, in the case of 17 percent, are simply scrapped. Why? When designing a board, you may face having to use different design tools for…
DesignCon video: Oscilloscopes and DDR5
At DesignCon 2020, Keysight Technologies demonstrated hardware and software products for signal integrity design and test. Keysight manufactures many oscilloscopes. While most are real-time oscilloscopes, the company also manufactures equivalent-time sampling models used for measurement and analysis of serial data streams. Here, Director Strategic Planning – Internet Infrastructure Brig Asay explains the difference between the…
“Engineering Big Ideas” video series: Prototyping tangible products with crowd funding
Mouser Electronics Inc. and celebrity engineer Grant Imahara unveiled the third video in the Engineering Big Ideas series, part of their award-winning Empowering Innovation Together™ program. In part three, Imahara meets with Josh Lifton, President of Crowd Supply, a successful crowd funding platform based in Portland, Ore. Crowd Supply partners with creators and entrepreneurs who […]
How do sensors for magnetic sensing applications work? Pt 2
At Sensors Expo 2019, Neil Cersell, President of the Cersell Company Inc., explains his company’s magnetic sensors that are available beyond the magnetic actuation market (Pt 1). With the three-wire, solid-state sensor, Cersell solves a rather simple but costly problem. In the North American market, a PNP type is prevalent and in the European market, […]
Teardown: Dr. Pocket TENS therapy pain relief kit
The electronic TENS (transcutaneous electrical nerve stimulation) therapy pain relief kit called Dr. Pocket uses electronic pulse stimulation via TENS to deliver electric impulses through electrodes in a pad that sits on the user’s skin. This device has multiple modes of different pulse frequencies covering transcutaneous electrical nerve stimulation and powered muscle stimulation which are […]
What information does a proximal flow sensor provide?
At Sensors Expo 2019 in San Jose, CA, Lucas Tschuor, Head of Field Application Engineering at Sensirion, explains how his company’s proximal flow sensor is used in respiratory applications with the help of a teddy bear. With a very sensitive device, breathing cycles can be detected and help the patient breathe providing an ideal sensor […]
How can you have touchless touch sensing?
At Sensors Expo 2019 in San Jose, CA, Håkan Persson, CEO of Neonode Inc., demonstrates touchless sensing using his company’s vertical-cavity surface-emitting laser (VCSEL) technology. Neonode’s zForce® (zero force) patented optical sensing technology uses infrared light, invisible to the human eye to provide a holographic touch screen, essentially making air touchable. The holographic design consists […]
