Multi-mode RF front-end module for NB-IoT1/2 and LTE Cat-M1/2 3GPP standards
Date: 05/10/2023
Qorvo announced its new multi-band multi-mode RF front end (RFFE) module optimized for NB-IoT1/2 and LTE Cat-M1/2 3GPP standards. Measuring 3 mm x 3 mm size, low 2.5V operation and supporting multi-band this device is suggested as ideal for low-voltage applications such as smart meters, asset tracking and monitoring, wearables and smart infrastructure.
The QM55011 delivers expanded NB-IoT and LTE-M operation down to 2.5V, enabling a broader range of battery options and eliminating the size and cost associated with boost converters. Its low power consumption extends battery life for applications where chargers and main power are unavailable. The device is capable of lower voltage operation under certain NB-IoT/LTE-M uses cases. It is also capable of supporting other air standards such as non-terrestrial network (NTN) and Wireless Smart Utility Network (Wi-SUN).
Tony Testa, general manager of Qorvo's Connectivity Components business, said “Customers bringing to market the next wave of battery-powered cellular IoT devices require reduced solution size and lower power consumption. The QM55011 delivers both of these along with extensive support for a full range of cellular frequencies.”
The QM55011 supports low-band (663 to 915 MHz) and mid-band (1695 to 2010 MHz) operations including the addition of B65 over previous product offerings. It includes integrated TX harmonic rejection filters and an antenna switch with auxiliary TX/RX paths which can support 2G power handling and a broad frequency range for bolt-on power amplifiers (Pas). Its band-select and bias are programmed through a mobile industry processor interface (MIPI).
