  1. A Quantitative Analysis Of The Power Advantage Of Hybrid Beamforming 4/19/2022

    In this white paper, a comparison focused on the power efficiency of analog, digital, and hybrid beamforming architectures is presented. A detailed equation-based model for the power consumption of the three architectures was developed for a receive phased array. There are downsides of going the hybrid route, but those trade-offs are likely to be worth the power savings for many applications.

  2. Multichannel Phase Noise Model Validated In A 16-Channel Demonstrator 4/19/2022

    This article details a systematic approach for predicting phase noise in large multichannel systems and compares it with measurements on a 16-channel S-band demonstrator. This analytic approach is based on a small set of measurements that can be used to estimate correlated vs. uncorrelated noise contributions.

  3. Understanding Phase Noise Fundamentals 3/9/2022

    A stable frequency source is a common requirement for many electronic and most RF devices. Phase noise is the term used to describe measurements of the short-term frequency stability of these sources. This white paper provides a brief technical introduction to phase noise concepts as well as an overview of how phase noise is measured and reported.

  4. Further Increase MLCC Reliability With CSAM Testing 2/2/2022

    As a result of tacking many layers of dielectric and electrodes on top one another, there are a number of issues that can be introduced during the manufacturing process that are not problematic when working with SLCs.

  5. 5G User Equipment Power Amplifier R&D Testing 2/2/2022

    5G New Radio (NR) presents dramatic challenges to the testing of User Equipment (UE) Power Amplifier (PA). This application note introduces an example of automated testing of 5G UE PA with R&S signal generator, signal and spectrum analyzer, vector signal explorer software, and power meters/power supply.

  6. The Cold Source Technique For Noise Figure Measurements 2/2/2022

    To make a noise figure measurement using the cold source technique there is a need to convert between different quantities such as noise figure, noise factor, noise temperature, linear gain, logarithmic gain, linear power, logarithmic power and so on.

  7. Radio Architecture Matters: A Review Of RF Sampling Vs. Zero-IF 1/19/2022

    The growing demand for wireless services not only challenges our limited spectral resources, it also challenges the radio designer to select the correct radio architecture. This article will examine two common radio architectures and learn how each solves the unique challenge of growing co-location issues.
