TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• Circuit Models For Plastic Packaged Microwave Diodes

  This paper reports on the measurement and establishment of circuit models for SOT-23 and SOD-323 packaged diodes. Results indicate that the 1.5 nH estimate for the SOT-23 is a useful result, as is 1.2 nH for SOD-323 single packaged diodes. It was also determined that the effective inductance of the SOT-23 may be reduced to approximately 0.4 nH by adding a second bond wire and modifying the microstrip line. Other lead configurations, including parallel bond wires and common cathode configurations, were also studied.

• How To Test USB Power Delivery Over Type-C

  USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.

• 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.

• Wi-Fi Performance In A House With Two Routers

  Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. This example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth.

• 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.
