Reliable and Flexible Simulation of Angle of Arrival (AoA)

Engineers often need to test the direction finding capabilities of radar warning receivers in the lab. A perfect solution is to use multiple coupled R&S®SMW200A vector signal generators that are phase-coherent and time-synchronized. This setup enables simulation of the angle of arrival (AoA) of radar signals in the lab.

Millimeter-Wave Receiver Calibration Made Easier, Cheaper, and Faster

Keysight’s new RCal helps you easily calibrate out errors from your measurement setup, improving your test Rx system accuracy by 10X. See the true performance of your device by moving your measurement plane from the signal analyzer input directly to the output of your device.

RF/Microwave Technology Driving the Connected Car

In-car networks and advanced driver-assist systems (ADAS) present many design challenges to engineers. This white paper looks at Cadence® AWR Design Environment® software solutions for RF to millimeter-wave (mmWave) front-end component development that address electronic product development for automotive applications.

NewSpace Terminal Testing Challenges and Considerations

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

Flying an Agile RF Transceiver in Space

ADI’s unique commercial space flow enables satellite bus and payload builders to integrate a modern solution rapidly that meets the specific needs of the newest generation of on-orbit space vehicles. Aside from the process, we’ll explain the rationale behind having two commercial space flows on the impacts on RF and Microwave products.

Application Note: Improving R&S®FSWP Measurement Speed

For automated test applications, measurement time is often as important as the quality of the measurement. In practice, phase noise measurements are generally not considered fast, but test engineers still desire to save as much test time as possible. With this paper you get a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurement speed.

Time Domain Analysis with a VNA

A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode – using the advanced inverse Chirp z-transformation, the measurements can also be simultaneously analyzed in the time domain mode. This gives the added advantage where the two fundamental modes of analysis can be performed by one single instrument.

Advanced Methods for Analyzing Ultra Wide Automotive Radar Signals

Review of different ways to overcome the challenges of RF measurements in the E band for ultra wide signals. It will look at the demodulation, analysis of a wideband automotive radar signal and discuss the results and main performance parameters.

Solving the Challenge of Many Devices with Multiple Standards in the Connected Home

Qorvo's ConcurrentConnect™ technology delivers seamless operation of IoT devices that are connected via different networks without performance loss. Its multi-standard capabilities fluently and continuously service multiple networks using different protocols, e.g. Zigbee + CHIP or Zigbee + Bluetooth® Low Energy to a smartphone, or other multi-network protocol use cases.

LoRa® Connectivity Made Smarter with Low-power, Front-end Modules

LoRa, short for long range, is a low-power wide-area networking (LPWAN) technology operating in unlicensed ISM bands that is rapidly gaining traction within the internet of things (IoT). Devices deployed on LoRaWAN networks follow the LoRaWAN protocol specification as defined by the LoRa Alliance®, a technology alliance of more than 500 members.
