With this essential guide, you'll have all the tools you need to build a solid foundation of 6G knowledge.


The Importance of Low Phase Noise and How to Measure It

Phase noise is caused by an RF waveform’s unintentional phase modulation, degrading the overall fidelity of a signal. In this white paper, learn phase noise fundamentals, how phase noise impacts the performance of radar and digital communications systems, and the limitations and advantages of two different phase noise measurement methods.


Conducted Emissions in DC/DC Converters - Simulation Versus Measurement

Simulation can be a big time-saver when designing EMI filters for DC/DC converters. Power supply control chip vendors offer various filter design tools that provide reasonable design choices for filter simulation before any hardware prototype is available. However, simulated results can differ significantly for different tools if simulated models are not accurate or do not cover all the relevant components.

Explore the current status of UAVs and the emerging trends in UAV wireless communication, focusing on the utilization of the ISM frequency band and mobile networks for seamless connectivity.


Standardizing Space Ovenized Crystal Oscillators for Lower Cost and Faster Delivery

Building for space is challenging. Program management requirements, parts availability and delivery, parts costs, and testing costs historically make space OCXOs expensive and longlead. Standardizing specifications based on MIL-PRF-55310, NASA EEE-INST-002, NASA Parts Selection List, and GSFC Preferred Parts Lists, and procuring parts to vendors standard drawings can significantly reduce costs and improve delivery of high-performance OCXOs.

Over-the-Air Pattern Measurements for a 32-Element Hybrid Beamforming Phased Array

In this paper we summarize measured receive antenna performance for a commercially available 32-element phased array demonstrator. The demonstrator is configured for hybrid beamforming with eight elements per subarray and four digital channels. The test setup and calibration steps are explained sequentially along with the measured calibration accuracy achieved. Three-dimensional radiation patterns of the antenna array are shown for various electronically steered beam positions including amplitude tapering.

Practical Considerations in the Design and Development of High Frequency Power Splitters

Recent trends and developments, such as 5G deployment, massive MIMO and beamforming, automotive radar, and space applications, are shaping the field of RF communications of the 21st century, particularly in the context of millimeter waves. In this article, the concept of a conventional surface mount planar Wilkinson power splitter is revisited and examined at frequencies above 20 GHz. 


Wilkinson Power Dividers and Feed Networks: A Brief Overview

Wilkinson Power Divider’s are widely used in many RF and microwave communication systems, including those with multiple channels or complex feed networks. Learn more about how Wilkinson Power Dividers work and how they play a crucial role in overall device performance.


Smart Microwave Antennas are a Step Closer with Advanced Dual Beamforming DAC

A technical collaboration between Teledyne e2v, France, and Fraunhofer IIS, Germany, recently evaluated the performance of a four-channel digitally steered 2.4 GHz planar antenna system. In this, a pair of state-of-the-art, gigahertz capable, digitalto-analog converters (EV12DD700) featuring a slew of novel, on-chip digital beamforming controls delivered digital beam steering control. The aim - to gain further validation of Teledyne e2V’s advance towards microwave RF softwarization.
