TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Quantum-Enabled Radar Research: Finding The Right Solution

  Examine how high-precision measurement of oscillators helped UK Quantum Technology Hub research to develop high-precision radar for detecting small objects such as drones and birds.

• Harmonic Measurement For IEC 61000-4-3 And Other Radiated Immunity Standards

  Amplifiers exhibiting significant harmonic distortion in immunity test systems can exhibit broadband characteristics that result in measurement uncertainty and unacceptable errors. This app note addresses acceptable harmonic measurement standards and other radiated immunity standards.

• Voltage Standing Wave Ratio (VSWR) Explained

  Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

  Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.
