RF Power Amplification 101: Waveform Basics

High-power RF generation is required not only by various wireless communication applications, such as 4G and 5G cellular and satellite, but also by radar for airspace and weather monitoring, radar and communication jamming, imaging, DC/DC conversion, and even RF heating.

Consider The Source: Reliable Network Analysis Starts With A Clean Signal

In wireless and satellite applications where speed, phase performance, and repeatability are critical, network analyzers with DDS sources deliver consistent results without the need for averaging. Digital-signal creation ensures low phase noise and fast frequency changes with continuous phase, reducing uncertainty in phase sensitive measurements.

Better Alternative For Measuring Linearity Of GaN Amplifiers

GaN devices continue to be a key element in many radar, electronic warfare, satellite, and terrestrial communication systems. This article focuses on the applications in which amplifier linearity is the critical attribute.

Expanding Filter Technology Offerings For Low-Frequency Applications
