Output Power Measurement on Noise Sources

Noise sources used for noise figure and gain measurements are typically controlled by the spectrum analyzer or noise figure meter instruments and are calibrated with their ENR value (Excess noise ratio). This application note describes a technique to perform a calibrated noise power measurement (P_hot) with spectrum analyzers and noise sources.

ONYX Oscillators in Low Earth Orbit

As access to and utilization of the low Earth orbit (LEO) region has expanded, so too has demand increased for affordable, mass producible space-worthy timing devices. In this white paper, Quantic Wenzel outlines the approach, process, and results of adapting and qualifying an established family of ONYX oscillators to production for commercial LEO space applications.

K-Band Microwave DACs Driving Quantum Computing Technologies

As classical computer developments asymptotically approach fundamental computational speed limits, quantum computing has the potential to be hundreds of millions of times faster, at a fraction of equivalent development costs. This will occur only if quantum computer designers can ensure microwave signal-source Qubit drive capability that is accurate, synchronized, reliable, and consistent.

Gate Drive Measurement Considerations

The more successful a gate driver is in reducing power-up and power-down times, the bigger the headache for accurate measurements. Both choosing the right probe and optimizing the probing technique are significant factors in improving measurement accuracy. This white paper provides guidelines.

Secondary Surveillance Radar (SSR) RF Power Measurement Challenges

Design, Verification, Troubleshooting and Maintenance of secondary surveillance radar (e.g. IFF-based radar) has never been more demanding. Proper design and operation of SSR systems can mean the difference between life and death. To reduce the possibility of a catastrophic event, federal aviation safety standards require transponders to undergo periodic maintenance and calibration.

Using Wireless InSite® for Engineered Electromagnetic Surface Modeling

Wireless InSite supports the simulation of RF interactions with engineered electromagnetic surfaces (EES). This allows modeling of passive metasurfaces designed to optimize wireless communication coverage by manipulating how signals propagate through a scene. This paper demonstrates how Wireless InSite simulates and analyzes the channel characteristics of EES in any environment, including indoor, outdoor, outdoor to indoor, and others.
