China's leading filter technology company,AHYT has successfully developed the world's first pair of 5G n79 and WiFi 6 coexistence filter modules, which effectively meets the urgent needs of the next stage of 5G and WiFi ecological co-existence, and this is the first time in the world. This series of products creatively uses AHYT's first hybrid design (Hybrid) technology in the world, organically combines the electromagnetic and acoustic filtering principles in a RF front-end module for collaborative design, giving full play to their respective advantages in large bandwidth and high The performance characteristics of suppression have achieved effects that are impossible with traditional filter technology, and solved the world-class problems that hinder the further development of the wireless communication industry.
Previously, the traditional filter technology, whether it is a wideband filter (SPD/LTCC) or a narrowband filter (SAW/FBAR/BAW), could not meet the performance requirements of large bandwidth and high rejection at the same time. The ecological coexistence of standards such as 5G and WiFi puts forward new requirements for filter technology. For example, 5G n79 (4400-5000 MHz) and WiFi (5150-5850 MHz) frequency bands each have a large bandwidth of over 600 MHz and a transition band interval. At only 150 MHz, if the two systems need to work at the same time without mutual interference, not only the filter must achieve ultra-large bandwidth, but also high-speed roll-off and high rejection, which traditional filter technology cannot achieve.
The series of Hybrid module products launched by AHYT this time work in core frequency bands such as WiFi (5150-5850 MHz), 5G n79 (4400-5000 MHz), 5G n77 (3300-4200 MHz), which not only achieves high performance and large bandwidth , And provides high isolation and high suppression between frequency bands. Take the WiFi filter module as an example. Its size is only 1.6 x 0.8 mm, the insertion loss is 2 dB, and it has high rejection of up to 25 to 40 dB for the 5G n79 full frequency band. Similarly, the n79 filter module also achieves suppression of up to 25 to 40 dB for the entire WiFi frequency band.
For the first time in the world, this type of product successfully solved the major difficult requirements of 5G and other standards for the filtering function, and effectively made up for the shortcomings of traditional filter products. It will soon become the standard component of 5G official commercial terminals, and will be a development in the field of RF front-end Has a major milestone.
