TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• An Introduction To Direction Finding Methodologies

  All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• 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.
