What is RF GaN Semiconductor Device?
Over the last decade, Gallium Nitride (GaN) has flaunted the technology as the future for high power cellular base stations that will displace silicon LDMOS devices.
Gallium nitride—GaN is a material that is generally used in the production of semiconductor power devices as well as RF components and light-emitting diodes (LEDs). GaN has labeled with the capability to become the displacement technology for silicon semiconductors, mainly in power conversion, RF, and analog applications.
Seeing as the dawn of the electronics age since a hundred years ago, power design engineers have been on an expedition for the ideal switch that will rapidly and efficiently convert raw electrical energy into a controlled and useful flow of electrons.
GaN ascension to the forefront of the RF semiconductor industry comes at a crucial moment in the evolution of commercial wireless infrastructure. It is proven performance leadership over LDMOS technology that is driving its adoption within the newest generation of 4G LTE base stations.
Market Research Future (MRFR), asserts in its recently published research report, that the Global RF GaN (Gallium Nitride) arket is projected to grow at 21.6% CAGR, witnessing considerable growth over the review period. The market was assessed at USD 415.3 million in 2017 and is touted to reach USD 1295.5 million by 2023.
Drivers and Restraints
The past decade has exhibited significant growth in the RF GaN market, which has reshaped the RF power devices landscape. Demand for RF amplifiers with a higher rate of data transmission, higher frequency, and power has led to the expansion in GaN RF device technology. The numerous factors attributing to the growth of global RF GaN market are growing adoption of RF GaN power mechanisms for energy & power applications and increase in demand for IT & telecommunication equipment that employ RF GaN power devices. moreover, innovation in linearization and power efficiency of RF power amplifiers will create opportunities for major market players during the forecast period. The augmented demand for IT & telecommunication equipment and deployment of energy & power applications are poised to drive the market during forecast period. Developments in RF power amplifiers are projected to create an opportunity for RF GaN market. On the other hand, competition from silicon carbide (SiC) devices is expected to hinder the market during forecast period.
GaN Success or Advantages
It takes a suitably matched and configured driver to make sure that the switching device—GaN operates to its full qualifications and does not have unplanned issues. More commonly, the role of this driver in the device is to be the electrical line among the lower-voltage digital output of the microprocessor-based controller or the same circuitry and the higher-voltage with high current, slew-rate demands of the power-switching device.
With this, there is much more to the role of RF GaN device than this. The need for the current high enough rate to swiftly charge the input capacitance of the device and to turn it on, yet it must quickly and crisply pull that charge from the gate input without ringing or overshoot.
At most, the factors define the top-tier concerns of GaN devices and its advantages—
The maximum gate voltage allowable is the gate threshold voltage and the body diode voltage drop. The gate-source voltage for an improved GaN device is 6V, and this simplifies the challenge of generating the needed turn-on and turn-off voltages and electric. The gate voltage is also lower than it is for most power MOSFETs and has a lower negative temperature coefficient, which also simplifies driver-compensation issues.
GaN is also known for being used for LEDs, power electronics, and RF. While GaN-based power semiconductors are rising high, the RF version of GaN is also taking off. As per the research, in 2018, sales of RF GaN-enabled devices grew by 22%. By 2023, the RF GaN device market will surpass $1.7 billion, according to the firm. For these years, RF GaN was a niche-oriented technology used in the military/aerospace community, especially for radar.
