RF Power Amplification 101: Amplifier Classes

The purpose of the RF PA is to increase the power of the RF input signal. This is achieved by applying the signal to the gate. This article compares some of the common amplifier classes, starting with the most-linear but least-efficient Class A to the still-linear (due to the ideal transistor) but more-efficient Class F and inverse-F.

Countering RCIEDs with GaN’s Bandwidth & Power Density Advantages

Counter-RCIED devices used by the military and law enforcement rely on jamming wireless trigger signals. This article will discuss how GaN’s high-temperature reliability and power density capability enables jammer equipment to meet system SWaP-C requirements.

RF Power Amplification 101: Waveform Basics

RF power is delivered by the power amplifier (PA), the final stage of amplification before the antenna, with each application placing on the PA its own set of requirements in terms of frequency, bandwidth, load, power, efficiency, and linearity. This article is the first in a series that will discuss these considerations.

Integrated Expertise Delivers the Best GaN Solutions for X-Band PAs

Gallium nitride is the undisputed technology for achieving high-efficiency operation in high-frequency applications, such as those at X-band (8–12 GHz). But device selection for X-band applications doesn’t end with choosing the material technology, because turning the bulk material characteristics into high-performance GaN on SiC devices is quite another matter.

Requirements for Wideband Power Amplifiers Used in mMIMO Applications

To accommodate for the immense growth in data rates that future wireless communication systems require, PAs should be able to transmit multi-carrier and multi-mode signals that occupy the full frequency span of a given communication spectrum, while also meeting challenging power, efficiency, and linearity requirements.

GaN Solutions: Small Packages for Big Radar Challenges

AESA systems use active arrays, each with hundreds or even thousands of antennas. In many cases, the system is evaluated on the basis of size, weight, power, and cost (SWaP-C). The technology enabling the latest AESA radar systems must therefore offer significant benefits in terms of SWaP-C improvements.
