TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 5G New Radio Over-The-Air Base Station Receiver Tests

  This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.

• Speeding Up Reflection Measurements On Antenna Systems

  Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. This application note presents solutions for aiding fast and efficient reflection measurements on antenna systems to get it right the first time.

• 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.

• Technical Report: Simulation Of Plasma Materials In XFdtd

  This paper discusses the FDTD method to simulate the behavior of plasma materials using Remcom’s XFdtd 3D EM Simulation Software and presents validation in one and three dimensions.

• Combining On-Wafer VNA And Spectrum Analyzer Measurements

  This app note describes how S-parameters and spectrum analysis can be monitored simultaneously from 70 kHz to 110 GHz using the VectorStar ME7838A, the Spectrum Master MS2760A, and the Anritsu MN25110A W1 coaxial precision directional coupler.
