  1. GaN Solutions: Small Packages For Big Radar Challenges 4/13/2021

    The defense sector continues to grow, with various countries increasing their defense budgets and contributing to between 3% and 4% growth in 2020 to reach $1.9 trillion in total, according to consultancy Deloitte.

  2. Phased Array Beamforming ICs Simplify Antenna Design 4/12/2021

    Wireless communications and radar systems are facing increasing demands on antenna architectures, for example phased array, to improve performance. Many new applications will only be possible with antennas that consume less power in a lower profile than traditional mechanically steered dish antennas.

  3. The Power To Reduce: ADRF5740 Attenuator 4/12/2021

    The ADRF5740 does what its name suggests, it attenuates – lowers - the strength of incoming and outgoing RF signals. The ADRF5740 is part of a complete signal chain for just about any RF or microwave circuit from 10 MHz all the way up to 60 GHz.

  4. GaN Breaks Barriers—RF Power Amplifiers Go Wide And High 4/12/2021

    The increasing demand for higher data rates in telecommunications and higher resolution in industrial systems is pushing the frequency of operation higher for the electronics that support them. Many of these systems operate over a wide frequency spectrum and further increased bandwidth requirements are a common request for new designs. 

  5. What Is RF Testing? 4/12/2021

    RF testing is an important and necessary part of product development for those products intentionally or un-intentionally producing or subjected to RF. In many cases testing is based on harmonized national, and regional test standards, or on the basis of industry, or product families.

  6. Why GaN Is 5G’s Super ‘Power’: A Series 4/1/2021

    While some feel GaN is still a relatively new technology, many can't dispute how it's advanced to the head of the class. Gallium Nitride is a technology on the cusp of dethroning silicon LDMOS, which has been the material of choice in high power applications. 

  7. Fundamentals Of Radome And Bumper Measurements Using The R&S®QAR 3/26/2021

    Radome testing is a necessity, checking sensor components for radar compatibility. Previously, there were two methods used for testing. R&S introduces the R&S®QAR as another solution. 

  8. Amplifier Selection Tips For EMC Applications 3/26/2021

    When choosing an amplifier for EMC testing, there are various factors to consider. These factors can include technology, class of operation, good linearity and low harmonic distortion, modulation performance, multiple signal/tone applications, and more. 

  9. 5G Mobile Technology - More Devices, Speed And Mobility 3/11/2021

    From commerce to education, and from dating to personal fitness, the merger of computers and wireless cellular technology has changed nearly every aspect of society. Mobile and embedded device manufacturers are looking to the future of wireless cellular communications in order to provide bandwidth and latency benchmarks required for a genuinely mobile-centric world.

  10. Spurious Testing Of 5G Devices Using EMI Receivers 3/11/2021

    With all eyes on the 5G wave, there are challenges that engineers face when it comes to radiated spurious emission (RSE) testing, and RSE testing is only one component of performing fully-compliant EMC measurements. Discussed in this application note are the latest features available in EMI test receivers, why they matter to everyday EMC measurements, and how developers of fifth-generation (5G) wireless technology are chasing an aggressive and impressive vision.
