  1. Microwave Power Dividers And Couplers Tutorial

    Power dividers and couplers are straightforward passive components. To design a component with high performance, designers must give attention to design detail, design execution, and fabrication quality. This article discusses power dividers and couplers and defines related terminology.

  2. Considerations When Choosing An RF Power Amplifier

    This white paper talks about the important operating parameters to consider when choosing an amplifier, from operating efficiency and output power level to linearity and mismatch tolerance.

  3. Introduction To SAW Filter Theory And Design Techniques

    Tradeoffs must be considered when selecting the best filter for system design applications. SAW filter technology offers reduced size and weight, which results in lower overall costs. This paper presents general SAW theory and performance information.

  4. Paving The Way To Self-Driving Cars With Advanced Driver Assistance Systems

    The excitement about the future of self-driving cars can make it easy to overlook numerous short-term developments by automotive manufacturers. Collectively known as Advanced Driver Assistance Systems (ADAS), these developments must be able to make cars safer, and their gradual introduction must also improve road safety. In addition, ADAS features represent an evolution in vehicle sensing, intelligence, and control that will ultimately lead to self-driving cars. This white paper discusses the challenges in ADAS adoption, and the importance of using the most advanced technologies for its future.

  5. Automotive Quality Standards 101: What Does Qualification Really Get You?

    Today’s automotive sector has overtaken the computers and communications as the fastest-growing market for electronic systems. As car technologies advance towards sophisticated driver-assistance systems and self-driving cars, several design factors have become even more critical.

  6. Emerging Communication Technologies Enabling The Internet Of Things

    Some connected things requiring global coverage and/or mobility will use cellular technologies, but most IoT devices will use noncellular technologies, sharing frequencies in unlicensed bands to communicate with each other and with IoT applications. 

  7. High-Power RF Pulse Generation And Measurement

    AR now offers high-power solid state pulsed amplifiers at various frequency ranges and output power levels to meet several standards. This paper presents some features and benefits of AR’s new line of amplifiers, and how to generate high speed and accurate peak RF power measurement capabilities.

  8. Antenna Basics

    This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.

  9. How Accurate Is TDOA Geolocation?

    Time Difference Of Arrival (TDOA), also called multilateration, is a technique for RF emitter geolocation using three or more receivers with algorithms to locate a signal source from the different arrival times at the receivers. This article explains factors that can have an impact on overall TDOA accuracy.

  10. Machine Learning And RF Spectrum Intelligence Gathering

    To classify a signal in RF spectrum intelligence gathering, the user must recognize a specific pattern associated with the modulation. Additionally, to recognize a remarkable signal present in received data, the pattern must be distinguished from the noise. Pattern recognition is something that the human brain is good at, but it is more desirable to automate these applications for efficiency and to avoid errors cause by human fatigue.
