Thin film ceramic interposer design provides benefits in RF and microwave applications, including lowered signal losses, improved thermal management, and increased potential for component size reduction.

Directional couplers are passive devices used for sampling incident and reflected microwave power, conveniently and accurately, with minimal disturbance to the transmission line. They are used in many testing applications where power or frequency needs to be monitored, leveled, alarmed, or controlled.

Designing cabled systems for space vehicles involves addressing mechanical and environmental challenges, with available coaxial cable options aiding in balancing electrical and mechanical performance.

Connectors will influence RF test results in various and sometimes unpredictable ways. Test equipment can compensate for some of these influences but often with detrimental effects. This article discusses how connections will affect test results and why it is important to create a valid test environment.

This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT, and ZND.

Radio frequency (RF) technology plays a critical role in military vehicle applications, providing essential communication, navigation, and targeting capabilities.

While optocouplers have been the dominant signal isolation solution for a long time, a new breed of higher-performance CMOS isolator solutions will ultimately out-mode the venerable optocoupler.

The broadband hybrid fiber coax (HFC) network has had unprecedented increase in demand since March of 2021. Internet traffic has increased 25% to 45% around the world over this time. Multiple system operators (MSOs) around the globe are evaluating the latest DOCSIS® specifications to upgrade their current networks to meet this increased demand.
