A9108 is one of AMICCOM sub1GHz family. It integrates AMICCOM sub1GHz transceiver well and offers a low cost solution with advanced radio features such as high output power amplifier up to 20 dBm (433MHz band, excluding LPF and HPF) and low noise receiver (- 114 dBm @ 10Kbps, -110dBm @50Kbps). Therefore, A9108 is very suitable for long LOS (line-of-sight) applications without the need to add an external LNA or PA.
The on-chip data rate divider supports programmable on-air data rates from 2K to 250Kbps to satisfy different system requirements. For a battery powered system, A9108 supports fast PLL settling time (35 us), Xtal settling time (500 us) and on-chip Regulator settling time (450 us) to reduce average power consumption.Features:
