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.
Perform High Impedance Measurements With Spectrum Analyzers
Modern RF circuit designs can use oscilloscope probes to directly probe circuit components, eliminating the need for traditional RF connectors and ensuring accurate measurements with high-impedance probes and spectrum analyzers.
Four Practical Applications Using An Electronic Load
This article presents four tips on how to test with electronic loads and illustrate the flexibility and usefulness of a DC electronic load.
Transmit And Receive Testing Of Digital Waveforms Using R&S®CMA180
The compact R&S®CMA180 Radio Test Set allows straightforward tests on devices that use analog or digital modulation and demodulation formats. This application note focuses on the use of the digital radio capabilities for measurements on radio transceiving devices in terms of their functionality and parameter characterization. Also shown is how to use the instrument with the various software tools available from Rohde & Schwarz for creating and evaluating digitally modulated signals.
