Mobile RF Architecture Analysis report of the Samsung Galaxy S26 Ultra Smartphone contains block-level schematic of the Cellular/Wi-Fi/BT RF paths.

The following is a Mobile RF Architecture Analysis report of the Samsung Galaxy S26 Ultra (SM-S948U) Smartphone.

The S26 Ultras (SM-948U) is Samsung's 2026 flagship smartphone for the United States market. This Qualcomm antenna-to-modem solution is based on the Snapdragon 8 Elite Gen 5 platform and is FR2 enabled. The SD R875 FR1/FR2 converged RF Transceiver is paired with Qualcomm’s latest Antenna-in-Package (AiP) component, the QTM575.

This report contains a block-level schematic of the Cellular/Wi-Fi/BT RF paths from the antennae to the RF Transceiver. Passive components are shown in the paths; however, the component values are absent. Component connectivity was achieved through full delayering of the smartphone printed circuit boards (PCBs).
