GaN is the third-generation of semiconductor materials. It has a broad forbidden band width. This material also offers superior properties to Si (first-generation) and GaAs (second-generation).
GaN can operate above 200°C thanks to its large band gaps and high thermal conductivity. It can provide higher energy density as well as higher reliability. Devices with a wider forbidden band and lower dielectric breakdown electric fields have lower on-resistance. High speeds of electron saturation, high carrier mobility and fast electron saturation allow for the device’s high energy efficiency.
GaN is therefore a good choice for people looking to get semiconductor devices with higher bandwidth and amplifier gain. They also have smaller sizes which are consistent with the consistency of “tonality”, the term used in the semiconductor industry.
The RF GaN technology matches perfectly with 5G. Additionally, the base station’s power amplifier is made of GaN. For radio frequency applications, semiconductor materials that are used in common use include: gallium trinitride (GaN), Gallium arsenide [GaAs], and Indium phosphide (“InP”).
GaN produces more power than the high frequency processes of gallium arsenide, indium phosphide, and silicon carbide. However, GaN displays better frequency characteristics than power processes such LDCMOS or SiC. GaN devices offer greater bandwidth, and can also be equipped with carrier aggregation or the ability to prepare higher frequency carriers.
You can use gallium-nitride faster than any other device or silicon. GaN can reach higher power densities. GaN offers the benefit of small dimensions for power levels. The device capacitance of smaller devices can be reduced making it easy to design systems with higher bandwidth. The power amplifier (PA) plays a crucial role in an RF circuit.
From the present application perspective, the power amp consists primarily of a gaium arsenide powered amplifier and a complimentary metal oxide power amplifier (CMOSPA). GaAsPA dominates but, with 5G’s advent, GaAs will no longer be able to sustain high integration at very high frequencies.
GaN then becomes the hot spot. GaN’s wide-bandgap nature means that it can withstand higher operating currents.
Qualcomm President Cristiano Amon stated that at the Qualcomm4G /5G Summit the Wave of Two 5G Mobile Phones (Wave 1) will hit the market between Christmas and New Year. Also, commercial 5G devices will launch in the First Half of 2019. According to reports, 5G technology can deliver speeds between 10 and 100 times that of current 4G networks. This will allow for faster data transfer rates, as well as reaching the Gigabit every second level.
Additionally to the increase in RF devices needed for the display of base-station RF transceiver and unit units, base stations density will rise as well. So, in comparison to the 3G or 4G eras, the number and density of 5G-era RF transceiver units will rise dramatically. Cost control is crucial, which is why silicon-based GaN offers a significant cost advantage. As silicon-based GaN technology matures, the company can reach market breakthroughs at the highest cost.
Looking at the past two generations, you can see that every generation of semiconductor technology has to be brought onto the marketplace. GaN at present is in this same stage. With increasing demand and process innovation, the cost to civilians will increase. In the end, the market will become the new market for silicon-based power device.
