摘要：

A SAW-Less NB-IoT transceiver for IoT devices with >10 years battery life and >164dB MCL is presented. Tunable RX Front-end supports 26 NB-IoT bands, achieves <-140dBm Narrowband Reference Signal Received Power (NRSRP) and tolerates up to-15dBm out-of-band blocking. RX phase continuity across sub-frames reduces RX power consumption by 30%. The Polar TX achieves >+4dBm output power, <5% EVM, and <-57dB 300kHz SEM. The 55nm transceiver consumes 11.8mW/25.8mW for receiving / transmitting, and occupies 2.23mm(2) die area in a 5.6x5.6mm(2) packaged chip.
