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.

Design Of A Complete RF Downconverter Module For Test Equipment
The example module and its constituent parts were designed and simulated with AWR Design Environment software using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks.

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.
