The SMM100A series of vector signal generators from Rohde & Schwarz have models that generate RF signals from 100 kHz with a high-end model to 44 GHz. That covers today’s 5G frequencies and more.
Passive-diode mixer covers 5G mmWave
The MAMX-011043 image-reject passive-diode mixer from MACOM covers 5G mmWave frequencies.
Spectrum analyzers for mmWave engineers use oscilloscope front ends
Keysight Technologies has created a slim version of its high-bandwidth oscilloscopes for analyzing wireless signals, including 5G NR. When you think of high-bandwidth oscilloscopes, you may think that their sole use is for measuring the integrity of baseband digital signals—in the time domain. RF engineers typically work in the frequency domain using swept or real-time…
Record and analyze signals to 26.5 GHz
The Tektronix RSA7100B wideband RF signal analyzer and streaming recorder lets engineers working on wideband designs in communications, radar, and electronic warfare capture and analyze signal in the frequency domain. It provides more than 2.5 hours of streaming RF storage with 800-MHz real-time bandwidth. Its 16 kHz to 26.5 GHz frequency range covers a broad…
Signal Generators cover 5G FR1 and FR2
The Model 865 from Berkeley Nucleonics lets you generate signals in the sub-6 GHz FR1 band and the mmWave FR2 band for testing 5G and other RF devices and systems such as Radar. 5G starts with RF/microwave/mmWave carriers and engineers need to test devices and systems with clean signals. For example, you might want to…
Isolators cut reverse-traveling signals at mmWave frequencies
To minimize issues from standing waves, engineers have long used Faraday rotation isolators that let forward-traveling signals pass to the load while attenuating reverse-traveling signals such as reflections. Higher frequencies, however, bring a new set of problems such as insertion loss that Micro Harmonics claims to have solved with its mmWave isolators. The series consists…
Mountain Home AFB: First to Use Portable Doppler Radar for CONUS Ops
Weather can be an unrelenting force and infamously fickle. Severe weather can adversely affect the safety of aircrew and Airmen working in the elements. Fortunately, advanced radars with weather forecasting capabilities can mitigate the associated risks. Keeping constant surveillance on weather patterns and their potential hazards is an important step in enhancing readiness and safety…
Radar Sensor Module to Bring Added Safety to Autonomous Driving
When a child runs out onto the road, the average human driver takes 1.6 seconds to hit the brake pedal. The reaction time is cut to 0.5 seconds for automated vehicles fitted with radar/lidar sensors and a camera system. But at a speed of 50 km/h, that still means that the vehicle will continue for…
A Smart Radar System for Gesture Recognition and Non-Contact Vital Signs Monitoring
This week, at FutureSummits 2019, imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, presents a compact highly-sensitive 140GHz MIMO (multiple-input multiple-output) radar system. The MIMO setup is demonstrated for gesture recognition, supporting intuitive man-machine interactions. In addition, the ultra-fine resolution of this radar allows the detection micro-skin movements related to vital…
Radar Can Wirelessly Monitor Your Vital Signs While You Sleep
University of Waterloo researchers have developed a radar system that monitors patients’ vital signs wirelessly, which eliminates the need to be hooked up to machines. The radar system is enclosed in a device that’s smaller than a smartphone, according to the University of Waterloo, and sends radar waves that record breathing and heart rates. Then,…
