Why GaN is needed in the 5G era! [Copy link]

GaN seems to be getting hotter with the upcoming 5G, but not many people know why it is so popular.

However , the reasons given in “ This is why the 5G era needs GaN! ” are very sufficient. For example:

GaN offers multiple advantages for 5G sub-6GHz massive MIMO base station applications:

• GaN performs well at frequencies of 3.5 GHz and above, while LDMOS is challenged at these high frequencies.

• GaN has high breakdown voltage, high current density, high transition frequency, low on-resistance and low parasitic capacitance. These characteristics can be converted into high output power, wide bandwidth and high efficiency.

• The GaN in Doherty PA configuration achieves an average efficiency of 50%~60% at 100W output power, significantly reducing transmit power consumption.

• The high power density of GaN PAs enables small form factors that require less printed circuit board (PCB) space.

• Using GaN in a Doherty PA configuration allows the use of quad flat no-lead (QFN) plastic packages instead of expensive ceramic packages.

• GaN's efficiency at high frequencies and wide bandwidths means massive MIMO systems can be more compact. GaN can operate reliably at higher operating temperatures, which means it can use smaller heat sinks. This allows for more compact form factors.

I have only summarized it here. What do you think? If you want to know more details, you can click the link to learn more. Do you think GaN will be a component that will inevitably be used in 5G in the future? Let's discuss it together!

As the frequency increases, all major manufacturers are moving towards high voltage, high power and high efficiency. NXP and other manufacturers are now working on 50V or even higher voltages. Traditional LDMOS is bound to make concessions. This trend is certain.
