The B40NLL_NBIOT_TRX is a sub-1GHz (699MHz-960MHz) fully integrated transceiver specially designed for Narrow-band IOT applications. The device is comprised of RF frontend, Frac-N frequency synthesizers, LO chains, and analog baseband blocks. The receive path (RX) has high dynamic range and sensitivity. A zero-IF TX generates low EVM signals to drive the external power amplifier. The fully integrated Frac-N frequency synthesizers generates required low-phase-noise LO signals for TX and RX mixers.
B40NLL_NBIOT_TRX is developed on SMIC 40nm Low Leakage RF 1P7M process.
The supply voltage ranges from 2.8V to 3.6V. A 38.4MHz temperature controlled oscillator (TCXO) is used as a reference clock.
