Samsung starts mass producing 5G chips for mobile devices

Samsung unveiled in August of last year the Exynos Modem 5100, its first 5G modem that is fully compliant with 3GPP standards. Today, the South Korean tech giant announced that the modem is hitting mass production along with the Exynos RF 5500 single-chip radio frequency transceiver and Exynos SM 5800 supply modulator as part of its new 5G chip offerings for mobile devices.

Those chips are the same hardware components that power the Galaxy S10 5G that was recently launched in South Korea. The three chips all support 5G New Radio (5G-NR) sub-6-gigahertz (GHz) spectrum and legacy radio access technologies.

The Exynos Modem 5100, in particular, supports both sub-6GHz and mmWave spectrums as well as 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA and 4G LTE networks. Coupled with the Exynos RF 5500 and Exynos SM 5800 chips, the 5G chip technology promises to provide reliable performance, Samsung claims.

Samsung’s Exynos RF 5500, which is responsible for the transmission of data over cellular networks, includes 14 receiver paths for download with support for 4×4 MIMO (Multiple-Input, Multiple-Output) and higher-order 256 QAM (Quadrature Amplitude Modulation) scheme. Additionally, the Exynos SM 5800 is capable of reducing power consumption by up to 30%, according to Samsung, through adjustment of the supply voltage based on the modem’s RF input signal.
