Monarch 2 SiP
All-in-One 5G Massive IoT System-in-Package

All-in-One 5G Massive IoT System-in-Package

Monarch 2 SiP, SKY66431, is a multi-band, multi-chip system-in-package (SiP), supporting 5G massive IoT (LTE-M/NB-IoT) platforms, co-developed by Sequans and Skyworks. It integrates the entire RF front end, transceiver, power management, RAM memory, crystals, and baseband modem for an LTE multi-band radio operating in the 699 to 2200 MHz frequency range. Monarch 2 SiP complies with the ultra-low power and reduced complexity feature requirements of the 3GPP release 14 LTE-Advanced Pro standard that defines narrowband, low data rate LTE technology for machine-type-communications (MTC), and is upgradable to 3GPP release 15 and 16. Monarch 2 SiP’s very high level of integration results in an 8.8 x 11.3 x 1.585 mm (max) BGA package for an industry-leading compact size. Monarch 2 SiP also embeds a low power GNSS functionality.


Monarch 2 SiP is ideal for adding LTE-M and/or NB-IoT connectivity to IoT devices which require intermittent tracking, operate in harsh environments, are size-constrained, or run on batteries. As such, its ultra-low power consumption, support of private LTE networks, optional integrated SIM, and Ag-free high reliability composition makes it ideally suited for applications such as smart meters, industrial asset trackers, or home or industrial monitoring devices. Its industry-leading compact size, integrated GNSS, open SDK, and ultra-low power consumption makes it the ideal connectivity solution for space-constrained devices, including personal/pet/bike trackers or wearable medical devices.
