QM55011SR

RF Front End (LNA + PA) Overview

The QM55011SR is a hybrid, multi-band RF front-end module designed for cellular IoT applications. It supports NB-IoT Cat-NB1/NB2, LTE-M Cat-M1/Cat-M2, and Non-Terrestrial Networks (NTN). The device integrates low-band frequencies (5, 8, 12, 13, 14, 17, 18, 19, 20, 26, 27, 28, 71, 85) and mid-band frequencies (1, 2, 3, 4, 25, 39, 65, 66, 70). It features an SP6T antenna switch with 2-TX and 4-TRX configurations, integrated TX filtering for harmonic suppression, and MIPI RFFE v2.0 control. The component utilizes adaptive biasing for efficiency optimization within a compact 24-UFQFN package.
