Designing BUC/SSPAs for Airborne Applications

As we witness the evolution of integrated communication, we also observe the increased number of requirements for airborne microwave transmission, ranging from satellite to air-to-ground CDL band communications. Airborne applications introduce many challenging design constraints including increased temperature ranges, thermal management, vibration and shock, EMC/EMI, power requirements, and safety, all while maintaining portability as a key factor.

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.

Ease Design For Deterministic Latency In UltraFast Digitizing Systems

Discover how ultra-fast data conversion and signal processing systems can be designed to guarantee deterministic latency. Past efforts focused on increasing data transmission speeds and bandwidths but increasingly, modern applications now set an equally high value on determinism. This article considers determinism, at device level and expands on the topic of how ultra-fast data conversion and signal processing systems can be designed to guarantee deterministic latency.

Accurate Noise Figure Measurement in ERZIA K/Ka-Band Low Noise Amplifiers for Satcom Applications

A discussion of noise figure measurements includes a wide number of options, instrumentation, and techniques each with their own advantages and limitations. In this tech brief, we focus on non-cryogenic applications, with proven performance, that can be conducted with standard laboratory equipment and easily followed by trained personnel.

Measurements on Devices with Very High Noise Figure

Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT.

Guide to RF Coaxial Connectors and Cables

RF coaxial connectors and cables provide vital RF links in communications, broadcast, EMC testing, commercial, military, and test & measurement. In this guide, you will learn the different types of RF Coaxial Connectors and Cables, the various uses for each, and how to choose connectors best suited for your application.

Third Order Intercept Measurements with a VNA

Third order intercept (IP3) is a hypothetical point at which the fundamental signal power and the third order signal power is the same. In practice, we can never reach this point as the amplifier saturates even before this condition occurs. However, IP3 plays an important role in characterizing the device.

Over-the-Air RF Conformance Measurements on 5G NR Devices

Read this white paper to learn more on over-the-air (OTA) testing on 5G NR devices. Focusing on RF conformance aspects and UEs, the paper examines the requirements described in the technical specifications. You will learn about antenna measurement key parameters, test methods and setups, and 3GPP OTA testing for UEs.

Reduce SWaP, Increase Performance of Phased Arrays with an Innovative Filtering Approach

The spectral environment is quickly changing today. It’s becoming more crowded, which is resulting in an increase in spectral noise. This is presenting a variety of new challenges for RF designers, both in terms of the architecture and power needed to transmit and receive signals and the types of jobs filters need to perform in receivers (Rx) and transmitters (Tx).
