QM55001SR

RF Front End (LNA + PA) Overview

The QM55001SR is a hybrid, multi-band RF front-end module designed for NB-IoT and Cat-M1 applications. It supports Low-Band frequencies ranging from 663 MHz to 915 MHz and Mid-Band frequencies from 1.695 GHz to 1.98 GHz. The component integrates power amplifiers, low-noise amplifiers, and switching functions within a compact 24-QFN (5x4) package. This configuration enables efficient signal transmission and reception for cellular IoT devices requiring broad frequency coverage.

RF Front End (LNA + PA) Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's current datasheet revision to confirm package type and tape-and-reel specifications. Ensure compatibility with MIPI RFFE v2.0 control interfaces if digital tuning is required. Cross-reference the exact frequency range requirements of the target application against the documented Low-Band and Mid-Band support to avoid integration errors.

RF Front End (LNA + PA) Selection Notes

Select this module when designing for NB-IoT or Cat-M1 networks requiring both Low-Band and Mid-Band support in a single component. It is suitable for space-constrained designs due to its 24-QFN footprint. Consider the integrated TX filtering capabilities if external filters are undesirable to reduce BOM complexity and improve spectral mask compliance.
