The company claims that its latest 5G modem supports networks including 5G’s sub-6GHz and mmWave spectrums to 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA and 4G LTE networks in a single chip

Samsung Electronics has announced that its 5G communication solutions are in mass production. The 5G multi-mode chipsets include the previously-introduced Exynos Modem 5100 as well as a new single-chip radio frequency transceiver, the Exynos RF 5500, and supply modulator solution, the Exynos SM 5800, all supporting 5G New Radio (5G-NR) sub-6-gigahertz (GHz) spectrum and legacy radio access technologies.

“Samsung has been an innovator in mobile communication technologies with a strong portfolio of market-proven solutions, and we are well-prepared to extend our leadership into 5G,” said Inyup Kang, president of System LSI Business at Samsung Electronics.

Kang added, “Our multi-mode solutions, the Exynos Modem 5100, Exynos RF 5500 and Exynos SM 5800 will together enable powerful yet energy-efficient 5G performance along with the network versatility that allows users to stay connected wherever they are.”

Exynos Modem 5100

Exynos Modem 5100 is Samsung’s first 5G modem solution that, as per the company, had completed preparations for commercialisation in August, 2018. Samsung is claiming that the modem supports virtually all networks from 5G’s sub-6GHz and mmWave spectrums to 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA and 4G LTE networks in a single chip. The modem is paired with RF and supply modulator solutions, Exynos RF 5500 and Exynos SM 5800 respectively.

Company’s official statement read, “Samsung’s Exynos RF 5500 supports legacy networks and 5G-NR sub-6GHz networks in a single chip, offering added flexibility in smartphone designs, especially for today’s premium mobile devices. RF transceivers are key components that allow smartphones to transmit and receive data over the cellular network. When transmitting voice or data from a smartphone to a carrier, the RF up-converts the modem’s baseband signal to high GHz-range cellular frequencies so that data can be sent swiftly over the connected network.

It added, “Vice versa, when receiving, the signal is down-converted by the RF to baseband frequencies for it to be processed by the modem. The Exynos RF 5500 has 14 receiver paths for download, and supports 4×4 MIMO (Multiple-Input, Multiple-Output) and higher-order 256 QAM (Quadrature Amplitude Modulation) scheme to maximize the data transfer rate over the 5G network.”

Exynos SM 5800

The Exynos SM 5800 is a low-power supply modulator solution for 2G to 5G-NR sub-6GHz that supports up to 100MHz envelope-tracking (ET) bandwidths. Samsung says that the Exynos SM 5800 demonstrates up to a 30-percent power reduction by dynamically adjusting the supply voltage according to the modem’s RF input signal.

Samsung’s official statement read, “Both the Exynos RF 5500 and SM 5800’s technological breakthroughs have been recognized by the International Solid-State Circuits Conference (ISSCC) committee and were presented at ISSCC 2019 held at San Francisco last February.”
