TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Ray-Optical Modeling Of Wireless Coverage Enhancement Using Engineered Electromagnetic Surfaces

  In this paper, results are presented of propagation experiments conducted to verify the accuracy of a novel ray-optical scattering model for EES.

• Qorvo Biotechnologies Sensor-Based Technology Provides Rapid Reference-Lab Quality Tests At Point-of-Care

  This white paper describes Qorvo Biotechnologies’ Bulk Acoustic Wave (BAW) immunosensor detection platform designed for point-of-care applications and describes analytical and functional sensitivity testing on human Thyroid Stimulating Hormone (hTSH) as an example. The Qorvo Biotechnologies’ platform is targeted to be central lab matched, with the goal of providing clinicians data that will enable quicker decision making across multiple disease states, such as in cardiac and infectious disease segments, where time to result and high performance are critical factors in the patient care workflow.

• RF Test Setup For Measuring Power & Harmonics

  Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

• 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.

• Accurate Test Fixture Characterization And De-Embedding

  This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.
