Product Overview
QM55011 is a hybrid, multi-band multi-chip RF front-end (RFFE) module supporting for NB-IoT1/2, Cat-M1/2 and NTN Non-Terrestrial-Networks application. The module supports LB (663MHz – 915MHz) and MB (1695MHz – 2010MHz). It has integrated harmonic rejection LPF, antenna switch and auxillary TX/RX path. QM55011 band select and bias are programmed through a Mobile Industry Processor Interface (MIPI).
