Palma Ceia SemiDesign offers a low power, 3GPP Release 14 NB-IOT (LTE Cat NB1) transceiver. The transceiver IP is targeted for the Internet of Things (IoT) and Machine-to-Machine (M2M) applications.
The transceiver performance conforms to the LTE NB-IOT specification, part of Release 14 from 3GPP for Low Power Wide Area (LPWA) applications that connect large numbers of sensor-type devices. The transceiver operates supporting both high- and low-bands compliant with the 3GPP Rel. 14 specification. The NB-IOT transceiver chip is single mode specifically for the bandwidth per channel and modulation requirements for NB1 and as such provides optimal power for the performance required. The transmitter offers high linearity, high output 1dB compression, high ACR, high power range and low noise. It includes necessary control for Carrier Suppression (CS) including the calibration path through the receiver. The receiver design offers high gain, high linearity, high selectivity, high signal range and low noise figure. The receiver has internal calibration schemes for DC offset correction and provides the necessary control knobs for IQ mismatch correction. The transceiver offers a low power profile including the radio and PA for +20dBm output. This solution is immune from reflected power concerns when the VSWR is diminished
