Most ADAS functions rely on radar sensors, and these safety-critical components must function correctly even under the most demanding of RF environments. This white paper describes a test procedure to replicate real life scenarios where the ADAS radar functions are activated during EMS testing and it contains some very interesting results.

RF data conversion systems are experiencing rapid changes as ADC and DAC performance specifications and form factors, along with new sensor technologies (Rx & Tx), continue to advance. One system level design problem has been consistent throughout—balancing the implementation tradeoffs between the analog and digital circuitry for maximum software/system flexibility (from sensor to the digital processing units’ input/output).

Accurate modeling and fast simulation of integrated passives on chips with growing RF content is critical. Read this Cadence white paper to learn how you can get highest-in-class accuracy and 10X faster EM simulation with foundry-certified technology.

5G is now and what’s next? As a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. Download this white paper to explore the evolution from 5G to 6G from a service, air interface and network perspective.

This eBook looks at a new antenna design that can connect to any mmWave module and provide better efficiency than patch antennas yet still fit into the compact size form factor for smartphones and other mobile devices. The first article covers the design requirements and challenges for mmWave 5G compact smartphone antennas. The need for mmWaves is outlined followed by a contrast of 4G and 5G architectures highlighting the differences in their antenna designs. Case studies of deployment scenarios for outdoor and indoor links are presented. A detailed set of requirements for antenna designs of future smartphones is discussed. Some previously reported candidate antenna designs are also reviewed. The second article provides specific compact wideband design examples and the third includes several pattern diversity architecture examples.

The Wilkinson Power Divider, designed by Ernest Wilkinson in the 1960s, uses quarter wave transformers to split an input signal into two equal phase output signals. Since the design is reciprocal, Wilkinson Power Dividers can also be used as a power combiner. With this flexibility, they are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks.

The family of ZNB vector network analyzers (VNA) from Rohde & Schwarz are the perfect instruments for analyzing RF amplifier small signal linear and non-linear performance. This application note presents information on how to configure and use the R&S® ZNB vector network analyzer to successfully make accurate and quick measurement of basic RF amplifier parameters.

With the rapid growth of wireless communication and sensing, there has been increased development of technologies at ever higher frequencies or smaller wavelengths. For example, high bandwidth communication addressed in the 5th Generation (5G) cellular network standards has motivated the opening of spectrum within the K and Ka bands (18-40 GHz). Whether repurposing existing lower frequency materials or developing new higher-frequency optimized materials, component developers need accurate material properties to use in their component designs.

Modern electronic equipment like Radar, Test and Measurement, Instrumentation, Avionics, require precision frequency sources with low phase noise. Although frequency accuracy and precision can be derived from atomic clocks, low phase noise often is not. NEL Frequency Controls Clean-Up VCXO bridges the gap by offering a complementary low phase noise solution to go along with use of atomic clocks. NEL’s application note “Crystal Oscillator Based Clean-up Modules” addresses improving the phase noise of atomic clocks as well as other types of precision frequency sources.
