Samsung says it’s now mass-producing its Exynos line of 5G modem and RF chips for mobile 5G solutions.
The Exynos multi-mode chipsets include the Exynos Modem 5100, which Samsung announced in August 2018, as well as two new additions: the single-chip Exynos RF 5500 radio frequency transceiver, and the supply modulator Exynos SM 5800 solution. All Exynos chips support 5G New Radio sub-6-gigahertz (GHz) spectrum and legacy radio access technologies.
The 5G Exynos Modem 5100 supports legacy radio access technologies in a single chip, including 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA and 4G LTE. The modem works at both sub-6 GHz and millimeter wave spectrum, and can deliver speeds between 1.6 - 6 Gbps, depending on network technology.
The Exynos RF 5500 supports legacy networks and 5G-NR sub-6GHz networks in a single chip, which Samsung claims will help support flexibility in smartphone designs. The RF chip has 14 receiver paths for download, and supports 4×4 MIMO and higher-order 256 QAM schemes.
The Exynos SM 5800 is a low-power supply modulator for 2G through 5G-NR sub-6 GHz networks. The solution offers up to 30% power reduction, and also supports up to 100MHz envelope-tracking (ET) bandwidths. Together, Samsung says its Exynos solutions help ensure data can be transmitted efficiently and reliably across 5G networks.
“Our multi-mode solutions will together enable powerful yet energy-efficient 5G performance along with the network versatility that allows users to stay connected wherever they are,” said Inyup Kang, president of system LSI business at Samsung Electronics, in a statement.
Both the Exynos RF 5500 and Exynos SM 5800 have been recognized by the the International Solid-State Circuits Conference (ISSCC) committee, according to Samsung, and were presented at ISSCC 2019 conference held earlier this year.
