Estimating Total Static Error For Skyworks Si89xx Series

This application note addresses the estimation of total static error for Skyworks' Si89xx series of isolated amplifiers and isolated delta-sigma modulators.

Best Practices For Using Preamps In RF Testing

Engineers performing RF enclosure, emissions, or field testing frequently will need to use a preamp with their receiver and associated antenna. Some best practices can improve results and avoid problems.

Overcoming Radar Simulation System Challenges

This article examines the challenges faced by EW system engineers in testing the effectiveness of their designs — in terms of technical demands, in-house capability, and, of course, cost.

Fast-Switching, High-Performance PLL And Quadband VCO Frequency Synthesizer

PLLs are used to generate RF and IF signals from less than 1 MHz to tens of GHz and higher. Application requirements vary widely, and PLL design and optimization involves trading off parameters such as power consumption, phase noise, frequency tuning range, frequency resolution, and lock time.

Industry Insights
Verifying The Clock Source

In order to select or develop a clock generator to use in your design or to ensure that the supplied system clock has the proper performance, you'll need to consider phase noise, jitter, wideband noise, and spurs as performance indicators.

5G RedCap: RF Implications For IoT Devices

Over the next few years, the global transition to 5G will expand in scope to cover many more applications. 5G Reduced Capability (RedCap) is a key step in this evolution.

Using A Hybrid Coupler In A Microwave Or RF Amplifier Test Setup

Hybrid couplers perform many functions, including splitting and combining signals in amplifiers, switching circuits, and antenna beam-forming networks in applications where power or frequency needs to be monitored, leveled, alarmed, and/or controlled.

Power Indication & Relative Accuracy In Amplifiers

The purpose and scope of this document is to explain amplifier power indication (metering) and typical variations associated with frequency sensitivity and bandwidth. Exodus amplifiers with our display/controller provide many monitoring and control functions.
