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.

• Power Consumption Analysis With Specialty DC Power Supplies

  Optimizing power consumption is critical for IoT devices running on small, non-rechargeable batteries. Learn how accurate characterization and smart design can extend device lifespans.

• 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.

• Basic Bulk Current Injection Testing

  Bulk current injection (BCI) testing is a conducted susceptibility procedure that uses an injection current probe. This paper provides an example of BCI testing, covering all steps, including gathering the required equipment, pre-calibration procedures, injection testing procedures, and safety precautions.

• Measurement Of The Phase Between Several Signals

  Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument.
