These past decade we as a society have been through a series of technological changes so big that we weren’t able to gauge the greatness of each one. The emergence of 4G technologies to leave behind 3G that used a silicon wafer to create an ultra fast network of communications was once.
And now, it’s 4G networks that have become old and slow, and 5G stands as a promise for the future. Nevertheless, there are several roadblocks to the development of 5G successfully, and some are deeply intricated with semiconductors. In this article, we’ll go over them.
Nowadays, nearly all mobile communications occur in 4G or the sub-3 GHz band. As a result, this band is too congested to meet the demands of growing mobile data traffic in the future.
To design next-generation cellular communication systems using the millimeter wave (mmW) frequency bands of 28 GHz and 39 GHz, a new paradigm has been investigated. This frequency is known as 5G.
The issue with 5G is that a number of special difficulties arise when using mmW semiconductor technologies.
Because electromagnetic (EM) wave propagation characteristics at mmW frequencies differ significantly from those of lower radio frequency bands, designing semiconductor circuits for 5G implementation at mmW frequencies presents a number of unique challenges.
Additionally, there are significant differences in the behavior of CMOS active and passive components at such high frequencies. These challenges must be fully understood when working on mmW frequencies.
Whether it’s to research the possibilities of Inalambrica networks, or to work with advanced devices, silicon wafers can help fulfill various roles. Here at Wafer World, we count with a variety of substrates in materials, size and applications. If you’re interested in learning more about what we have to offer, reach out!
