gallium nitride amplifier

Fairview Microwave's solid state GaN (Gallium Nitride) power amplifiers (also called SSPAs) feature broad frequency bands ranging from 30 MHz to 7.5 GHz and very high gain levels from 43 to 60 dB. These GaN SSPAs also show impressive harmonic response (-15 to In the speaker-driving section of the amplifier, Technics has employed a high-speed GaN (gallium nitride) FET driver device with super-low resistance. This enables the construction of a high-power amp using a single push-pull configuration, allowing the length of the large current carrying signal path to be shortened, and resulting in

Is GaN Replacing Silicon? The Applications and Limitations

Jan 23, 2019GaN transistors are also finding their way into radio applications due to their superior frequency characteristics with Comtech PST Corp. producing their model BPMC928109-1000 which is a GaN amplifier for use in speed cameras, air traffic control, and even military applications requiring frequencies between 9.2-10GHz at 10kW of power.

Jun 21, 2017REDONDO BEACH, Calif. – June 21, 2017 – Northrop Grumman Corporation business (NYSE: NOC), Microelectronics Products and Services (MPS) announced the availability of four new gallium nitride (GaN) power amplifiers, an upgraded amplifier, and two low noise amplifiers.

This power amplifier provides 20 decibels (dB) of linear gain, +36 dBm (4 watts) of output power at 1 dB gain compression and +38 dBm (6.3 W) in saturation with Physical Address Extension (PAE) of greater than 30 percent. The APN180 is a GaN HEMT MMIC power amplifier

Sep 01, 2017Gallium Nitride HEMTs are well suited for RF and high power applications due to its distinctive characteristics of wide band gap. Larger band gap of GaN yields higher breakdown field and drain current,,,, which makes the device to be a promising candidate for MMICs and RF amplifiers. The growth of HEMT took a decade of years.

Abstract: Gallium nitride (GaN) amplifiers are inherently well suited for high power applications, but their increased power densities call for high thermal conductivity (k) substrates, such as copper (Cu) or aluminum nitride (AlN), to provide adequate thermal management. Thus, low-cost/low-k substrates, such as organics, have been traditionally overlooked for GaN-based amplifiers.


Analog Predistortion Linearizer for a Gallium Nitride

A linearizer has been produced to linearize a 200W C Band Gallium Nitride solid state power amplifier. The design is developed based on the method of correcting phase and gain distortion. The linearizer successfully increases the effective output power of the amplifier by at least 1dB for 5.85GHz-6.725GHz, keeping IM3 levels at lower than -22dBc.

May 14, 2020Gallium Nitride (GaN) enables high power Class-D solutions with superior sound, efficiency, and thermal performance . OTTAWA, Ontario, May 14, 2020 – GaN Systems, the global leader in GaN (gallium nitride) power semiconductors, today announced the debut and availability of a new amplifier

Jul 07, 2020By incorporating the BOSC amplifier design (2x), the new Orchard Starkrimson system becomes the only integrated amplifier on the market which uses gallium nitride (GaN) technology. And in a unique and nice touch, the integrated amplifier still provides access to both the DAC outputs and the amplifier inputs to enable the connection of devices

There are many predictions that the RF GaN industry has been, and will continue, to experience substantial growth over the next several years. Predictions estimate that the currently nearly US$ 400 million RF GaN market (2017 close) will likely grow to, or beyond, US$ 1 billion by 2023 [1, 2]. With the defense industry consuming

The market for gallium nitride (GaN) devices will grow 17% a year to over $3.4bn by 2024 with four companies dominating, according to a new research report. The market for gallium nitride (GaN) semiconductors is largely consolidated, with the top four companies taking 65% of the overall market in 2015 says Transparency Market Research (TMR).

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. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks.
