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.

Five Factors to Consider when Selecting an Overcurrent Protective Device for an Electric Vehicle System to Ensure Safe and Reliable Performance

In electric and hybrid vehicle applications, electrical systems are often pushed to their limits. Aggressive current pulses, combined with high temperatures and vibration profiles, push the limits of electrical system reliability. When selecting an over-current protection device (OCPD), care must be taken to account for these complex variables while still providing a system that is safe and reliable. This article will discuss five critical and often overlooked factors in OCPD selection in EV applications in order to ensure safe and reliable system performance.

Selecting the Right Standard High-Voltage Power Supply

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.

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.
