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.

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.

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.

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.
