Aperture Tuning: An Essential Technology in 5G Smartphones

Aperture tuning is essential in enabling smartphones to operate efficiently over increasing RF frequency bands and support transitions to 5G. Proper tuning enables antennas to operate efficiently on multiple bands and increases Tx and Rx performance. Implementing aperture tuning requires in-depth knowledge of how to apply the technology for smartphone application.

Designing for EMI Testing (Step-by-Step Guide): Improve Your Time to Market With Oscilloscopes

The challenges in testing EMI during early product cycle are multifold. In our free step-by-step guide, we break down the whole EMI design test process into “Locate”, “Capture”, and “Analyze”. With this guide, you are now able to discover and analyze EMI in a more systematic and methodical approach.

Design and Physical Realization of Phased-Array Antennas for MIMO and Beam-Steering Applications

A phased-array antenna is made up of multiple individual radiating elements (antennas), each fed with an RF signal controlled through phase shifters in such a way that the radio waves from the separate antennas are added together to increase the radiation.

Realizing the SWaP-C Benefits of Designing with Positive Gain Slope MMIC Amplifiers

Modern wideband microwave systems often require a flat overall gain response with respect to frequency. Achieving this performance can be difficult, however, since most wideband microwave components exhibit a negative gain slope as the frequency increases.

Optimize Doherty Power Amplifiers

Speed up development, verify best performance and start up series production with confidence. Doherty designs achieve high efficiency, greater linearity and increased output power. Get deep insight into your design with a dual-path, precisely synchronized source driving the Doherty amplifier and improve your yield.

How to Optimize Measurement and Transactional Speed of Your DAQ

Get fast, quality measurements without a large DAQ mainframe system. Read tips about how to select the right hardware and how to configure it to increase your reading speed. Optimize your DAQ system for throughput, scanning speed, and accuracy with help from this white paper.

Seeing the Full Picture: Introducing Software-Defined Spectrum Analyzers

Wireless communications technology has become a vital component of today’s information driven world. With so much reliance on it, it’s easy to forget how different the spectrum environment looked only a few decades ago. This shift has also pushed spectrum monitoring requirements well beyond what was previously the norm.

RFIC PA Development for Communication and Radar Systems: Basic Operations and Metrics

Power amplifiers (PAs) are responsible for increasing the strength of a signal with minimal added distortion. By providing enough signal strength to overcome over-the-air losses, PAs play a vital role in the RF/microwave front end of any communication system.

How To Right-Size Your Wireless Testing

Whether mobile devices, Internet of Things, or industrial RF applications, the world runs on wireless. As a result, wireless testing is more important than ever before. But how do you balance thoroughness, speed, and budgets? Quipping "pick any two of the three" isn't a good answer.

MM-wave Partial Information De-embedding: Errors and Sensitivities

De-embedding methods making significant structural assumptions have become popular in mm-wave fixtures because of the relative immunity to repeatability and standards availability problems at the DUT. The intrinsic errors, repeatability and configuration sensitivities are studied in this work with examples in the WR-10 and WR-2.2 bands.
