The Qualcomm SDR875

Mobile Communication in Samsung Galaxy S24 Ultra

Exciting news has arrived in the world of mobile technology as Qualcomm's much-anticipated SDR875 transceiver is here after nearly a year of anticipation since its media announcement. This innovative FR2 IF and FR1 converged RF transceiver has finally landed in our labs, promising a new era of efficiency and performance for high-end smartphones.

Samsung's Galaxy S24 Ultra, available in the USA, Canada, and Korea, proudly leads the pack as the world's first device to integrate Qualcomm's unified solution, regardless of FR2 support. As a vital component of the Snapdragon X75 chipset, the SDR875 seamlessly combines the functionalities of two SDR735 sub-6 GHz transceivers with the FR2 (mm-wave) IF transceiver SMR546 on a single silicon die.

The advantages of this convergence are immediate and impressive: a smaller package, reduced power consumption, enhanced inventory control, decreased PCB real estate, and an optimized modem-to-transceiver interface. Samsung's decision to adopt this solution for their iconic flagship smartphone reaffirms Qualcomm's leadership position in the high-end market.

However, it's essential to note that variants of the Galaxy S24, such as the S24+ sold in the EU, utilize Samsung's Exynos 2400 mobile platform, featuring the FR1-capable Shannon S5540 transceiver.

For those eager to delve deeper into the technical aspects of the SDR875 transceiver, our preliminary analysis is available on the TechInsights platform, offering insights into its performance and impact on the mobile landscape.
