What is a gan amplifier

GaN-based semiconductor optical amplifiers SOAs have the ability to boost the output power of laser diodes and thus are candidates for a broad variety of potential uses. Applications that utilize short wavelength, ultrafast pulses, including microprocessing, orthoptics, and next-generation optical storage can most benefit from GaN-based SOAs since current ultrafast pulse sources rely on large, expensive solid-state lasers. GaN-based SOAs can generate high-energy, high peak power optical pulses when used in conjunction with mode-locked laser diodes. In this chapter, the basic characteristics of these devices are discussed, concentrating on pulse amplification. Early experimental work, as well as the latest results, is presented, and improvements in the SOA design allowing the generation of higher optical pulse energy are discussed.

INNOVATIVE GaN PRODUCTS


Satellite communication systems use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data. To attain this, they must deliver high RF output power while simultaneously ensuring the signals retain their desired characteristics. Nasdaq: MCHP helps meet both of these requirements. A balanced architecture allows the GMICP to be well matched to ohms and includes integrated DC blocking capacitors at the output to simplify design integration.

The company also provides compact models for the GMICP, which allow customers to model the performance and expedite the design of the power amplifier in their systems more easily.

Single-Ended, 2-Channel GaN Class D Amplifier – Evaluation Board

Potential applications include Hi-Fi amplifiers, AV receivers, Home theater systems, Powered speakers, Musical instrument amplifiers, and other premium audio designs. The reference design provides all the required housekeeping power supplies for ease of use. The 2-channel design is scalable for power and the number of channels. This topology represents an analog version of a second-order sigma-delta modulation, having a class D switching stage inside the loop. The benefit of the sigma-delta modulation, in comparison to the carrier-signal based modulation, is that all the error in the audible frequency range is shifted to the inaudible upper-frequency range by nature of its operation. Also, sigma-delta modulation enables the designer to apply sufficient error correction. Mike is the founder and editor of Electronics-Lab.

Radio waves were first mapped out and harnessed back in Since that time, radio frequencies and microwaves have been used in numerous applications from the telegraph and the first radio broadcasts making their way into people's homes to radar technology and musical instruments. They also paved the way for military drones, satellites, and the internet among other modern-day essentials. It's no secret that radio waves have little reach and effectiveness on their own. Because of this, RF power amplifiers are needed to increase their bandwidth or boost their power output, efficiency, and gain among other aspects. In the beginning, amplifiers relied on vacuum tubes and bipolar junction transistors. These days, the industry has moved on to bigger and better things, the most common of which are GaAs and GaN.

With GaN, the design is very efficient and operates without heatsinks. These features allow audio design engineers to create premium audio products at shorter time to market and at an affordable price. The convergence of audio trends including demand for more power, size and weight reduction, and growing consumer demand for better audio quality requires innovative approaches to enhance sound quality, increase efficiency, and reduce size which is served by GaN power semiconductors. Applications include smart speakers to automotive and high-end home audio systems.

The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride GaN as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF.

Both military and commercial configurations can benefit from improvements in:. Tracing their history back to Defense Advanced Research Project Agency DARPA investments in the mid s, the latest generation of GaN-based semiconductors available to component manufacturers, points the way to many next-generation systems including radar, communication and unmanned aerial vehicles UAVs. With 5 to 10 times the power handling capability, a GaN device can handle twice the voltage and current of a comparable GaAs device. Likewise, with nearly 7 times the thermal conductivity of GaAs, GaN components can operate at a much higher temperature. The result is a selection of adaptable, modular amplifiers requiring only a single supply voltage.

The RF GaN amplifier serves an important role in MPT transmission system. Recently, high-power and high-efficiency GaN amplifiers have been developed.

Benefits of GaN Transistors

The rapid spread of mobile terminals such as smartphones and tablets has required the establishment of earth stations for satellite communications systems SATCOM which is a means of high-speed communication in regions where it is geographically difficult to install more mobile communication system base stations, or to secure emergency communications and develop terrestrial communication networks. While power amplifiers using Si transistors have been employed in each of the systems, the switch to GaN amplifiers that employ GaN Gallium Nitride on transistors - which is expected to be more efficient and have higher output than Si - is gathering pace.

The module, which uses a minimum number of chips in the matching circuit to control high-quality signal output, is expected to help realize 5G base-stations that are widely deployable and highly power efficient. High-density mounting technology to realize compact PA module for more widely deployable 5G base-stations. In 4G base-stations, which do not use massive multiple-input and multiple-output mMIMO antennas, power amplifiers use metal-foil transmission lines for the matching circuit. While this lowers power loss resulting in high-efficiency operation , transmission lines take up space and make it difficult to realize base stations that are both extra small and extra power efficient.

GaN amplifiers

Gallium nitride GaN is a wide bandgap material that offers significant advantages in high-power radio frequency RF applications. Compared to traditional semiconductors such as silicon , gallium nitride has some very important physical and electrical properties, including:. Compared to traditional technologies, gallium nitride has proven to be a superior material for several applications in the radio frequency field, where reliability, efficiency and reduced absorption are essential requirements. Technology based on GaN-on-SiC is by far the most used, both because it combines the high-power density of gallium nitride with the low power losses of silicon carbide, and because it solves the issues related to thermal management and parasitic losses.
