  1. Doherty, Balanced, Push-Pull, And Spatial Amplifier Performance Enhancement

    This application note presents a hybrid simulation-/measurement- based development methodology used to achieve enhanced amplifier performance with linear form of pre-distortion. The approach shown may be combined with DPD to achieve an even better result. It may also be used to lower DPD requirements.

  2. Designing Microwave PCBs For Successful Manufacture — Getting It Right The First Time

    With improvements in processor speed and model accuracy, it is more common for microwave circuit simulations to bear close approximation to their eventual real-world performance. However, not all pitfalls present in the successful manufacture of a complex microwave circuit are captured in simulations. 

  3. Optimization Study Of A Diplexer

    The V14 release of the NI AWR Design Environment platform includes many optimizers that automate and streamline specific applications to help designers bring their products to market more quickly and cost effectively. 

  4. RF Board Connector: Footprint Optimization

    While low frequency/low data rate applications can use a generic footprint for RF board connectors, modern bandwidths that support data rate of 56 Gbps and beyond require an optimized footprint designed and matched to a specific board stackup.

  5. EMC Pre-Compliance Fundamentals

    By using a performance EMI receiver, independent compliance test laboratories and companies with in-house self-certification labs can make radiated and conducted emissions tests, certifying a product meets local regulatory compliance standards. Learn how to make EMC pre-compliance measurements with this white paper.

  6. 3 Tactics For Configuring Phase-Coherent RF Signal Generation

    This white paper will help the reader understand phase coherence and why it matters, and offer tactics for generating phase-coherent signals.

  7. Making EMI Compliance Measurements

    Electrical or electronic equipment that uses the public power grid or has potential for electromagnetic emissions must pass EMC (electromagnetic compatibility) requirements. These requirements fall into four broad types of testing: radiated and conducted emissions testing, and radiated and conducted immunity testing. Conducted emissions testing focuses on signals present on the AC mains that are generated by the equipment under test (EUT). This application note introduces the basics of EMI compliance measurements, as well as the measurement process and regulations.

  8. Glass Sidewall Packages Provide Performance For RF Applications

    Glass sidewall packages achieve highest levels of hermeticity for hardware in space vacuums and extreme temperatures. Compared to ceramic, they deliver better RF performance thanks to their lower dielectric constant.

  9. Highs And Lows Of Electronic Warfare

    The next chapter of electronic warfare is all about precision and low visibility. Col. Mark Dotson said the Army’s new EW strategy is centered on, “using low power to affect the signal and to affect it in such a way that it may not even be detectable that you’re interfering with what they’re doing.”

  10. 5G New Radio eBook

    Is 5G simply another generation of mobile communications technologies? Or something revolutionary? In this eBook, Rohde & Schwarz give insights into 5G New Radio (NR), exploring all of its relevant details, key implementation aspects, and required test and measurement equipment for the development of 5G NR products.
