This is an Ultra-Low-Power Cat-M (NB1 & NB2) UE RF Transceiver IP solution optimized for IoT and M2M applications. The RF IP supports Release-17 frequency bands with Integrated Power Amp. The NB-IoT RF IP supports wideband for the Receiver and the Transmitter path where the band limitation can be set by external components. This NB-IoT CAT RF solution has GNSS capabilities and can be integrate or upgrade with NTN (Non-Terrestrial Network).
The receive path (RX) has extremely high dynamic range and is implemented to support both direct-conversion and low-IF architectures. A direct conversion TX generates low EVM signals. The IP family has both options of integrated PA, and supporting external PA. An integrated Frac-N frequency synthesizers and LO-chains generate the required low phase-noise LO signals for TX and RX mixers. Optional fully integrated power management can be integrated to minimize the module eBOM cost.
The NB-IoT RF IP in combination with other wireless technologies like Bluetooth and GNSS enables various IoT based application from smart home to industrial automation, to battery powered applications like wearables etc. due to its lower power consumption.
