Additive Phase Noise in Amplifiers

Phase noise has been a growing concern for high-performance transceiver designs. This white paper will discuss and analyze the various sources of additive phase noise in RF amplifiers as well as typical application requirements and measurement challenges. Phase noise specifications for a series of MMIC amplifiers are presented.

Automatic Fixture Removal from VNA Measurements

Automatic Fixture Removal is a simple, accurate way to de-embed measurement fixtures. These are typically used when measuring SMD type components to provide an interface from the VNA test port cables to the DUT. The main challenge when characterizing such components is to completely isolate DUT characteristics from the fixture.

Improving R&S®FSWP Measurement Speed

The Rohde & Schwarz®FSWP (FSWP) is a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurements speed. However, several measurement settings drastically affect measurement speed. This paper will discuss these settings and provide suggestions on improving overall measurement speed.

NewSpace Terminal Testing Challenges and Considerations

Today’s satellite communication systems combine features from legacy cellular networks and emerging wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals (Figure 1). Each link in the supply chain presents unique challenges for R&D, production and deployment for both the components and system development.

Flying an Agile RF Transceiver in Space

ADI’s unique commercial space flow enables satellite bus and payload builders to integrate a modern solution rapidly that meets the specific needs of the newest generation of on-orbit space vehicles. Aside from the process, we’ll explain the rationale behind having two commercial space flows on the impacts on RF and Microwave products.

Application Note: Improving R&S®FSWP Measurement Speed

For automated test applications, measurement time is often as important as the quality of the measurement. In practice, phase noise measurements are generally not considered fast, but test engineers still desire to save as much test time as possible. With this paper you get a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurement speed.

Time Domain Analysis with a VNA

A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode – using the advanced inverse Chirp z-transformation, the measurements can also be simultaneously analyzed in the time domain mode. This gives the added advantage where the two fundamental modes of analysis can be performed by one single instrument.

Advanced Methods for Analyzing Ultra Wide Automotive Radar Signals

Review of different ways to overcome the challenges of RF measurements in the E band for ultra wide signals. It will look at the demodulation, analysis of a wideband automotive radar signal and discuss the results and main performance parameters.
