Introduction:
DL7612 is a low power,LoRaWAN based wireless communication module for 863-928MHz band. It
integrated with Semtech SX1276 RF chip and ambiQ micro Apollo1 MCU, DL7612 can achieve a
sensitivity of over -139dBm,The high sensitivity combined with the integrated +18.6dBm power amplifer
yields industry leading link budget making it optimal for any application requiring range or robustness.

1.General Description
The DL7612 incorporates the LoRaTMspread spectrum modem which is capable of achieving
significantly longer range than existing systems based on FSK modulation. At maximum data rates of
LoRaTMthe sensitivity is 8dB better than FSK, but using a low cost bill of materials can improve receiver
sensitivity. LoRaTMalso provides significant advances in selectivity and blocking performance, further
improving communication reliability. For maximum flexibility the user may decide on the spread
spectrum modulation bandwidth (BW), spreading factor (SF) and error correction rate (CR). Another
benefit of the spread modulation is that each spreading factor is orthogonal - thus multiple transmitted
signals can occupy the same channel without interfering. This also permits simple coexistence with
existing FSK based systems.The DL7612 offer bandwidth options ranging from 7.8 kHz to 500 kHz with
spreading factors ranging from 6 to 12, and covering upper UHF bands.
