RF Testing on Automotive Infotainment Devices

The car radio has evolved from a cassette player to a state of the art entertainment system, keeping the driver and passengers connected on the go. The entertainment system brings a design challenge in that communication and broadcast standards have to coexist within a small area in the dashboard of a car. Since the frequencies defined by the RF standards are in close proximity, it is very important that the frequencies coexist and since multiple standards need to be supported in the single assembly, RF modules are placed next to each other on the assembly line. Other than testing the entertainment center in the car, the antennas inside the car are subjected to cross-coupling effects with passengers mobile devices. To ensure the RF performance of the infotainment system, all of these scenarios need to be thoroughly tested. This application note highlights some of the RF measurement challenges and introduces equipment that is required for relevant RF characterization of car infotainment devices.

Direction Finding: Its Importance in Our Changing World

Direction finding is important for civilian, defense, and law enforcement purposes. It involves the use of specialized instruments, antennas, and methods to determine the physical location of a source of RF energy or target. A radio direction finder estimates the direction of an emitter by measuring and evaluating electromagnetic field parameters. This 10-minute audio-visual presentation looks at direction-finding methods, applications, configurations, and benefits. Viewers will be able to submit questions and download a new Rohde & Schwarz white paper that is an essential resource for understanding all aspects of direction finding.

The Ins and Outs of Spaceflight Passive Components and Assemblies

RF and microwave components deployed in space flight applications can experience hundreds of degrees of temperature variation, massive amounts of radiation, and can be expected to operate at an elevated level for sometimes decades. The demands of operating in a space environment bring many unique challenges and unforgiving reliability requirements; therefore, designing passive components to meet these rigorous operation criteria necessitates a high level of design expertise, qualifications/certifications, and testing capability.

Pulsed Phase Noise Measurements: Challenges and Solutions

Thanks to advances in digital signal processing techniques, wireless communications and radar systems have become increasingly digital. Constraints have also been placed on packing more information into less bandwidth. For both systems, one of the key RF parameters that limits performance is phase noise.

Conductive Coatings Protect Circuitry from EM/RF and ESD

With the trend toward smaller and smaller electronic devices, unintentional EMI/RFI interference has become more of an issue. Shielding of these interferences is critical and coatings can be successfully applied as protection on the materials used. In this paper, the different sources of interference are explored, as well as how coatings can play a critical role in protecting these sensitive components and boards.

Tiny Graphene Radios May Lead to Internet of Nano-Things

For wireless communication, we’re all stuck on the same traffic-clogged highway — it’s a section of the electromagnetic spectrum known as radio waves. Advancements have made the highway more efficient, but bandwidth issues persist as wireless devices proliferate and the demand for data grows. The solution may be a nearby, mostly untapped area of the electromagnetic spectrum known as the terahertz band.
