• Overview

• 
  

• The LoRa2021F33-2G4 is a transceiver module based on SEMTECH's LR2021 chip, which
  integrates the 4th-generation LoRa IP core and supports operation in the Sub-GHz and 1.9-2.5 GHz
  frequency bands, the L-band, and licensed S-band frequencies, making it suitable for both terrestrial
  and satellite communication (SATCOM) networks. In addition, the Lora2021F33-2G4 features extended

• physical-layer modulation capabilities to support Fast Long-Range Communication (FLRC). When integrated

• with third-party protocol stacks, it is compatible with a wide range of low-power wireless protocols, including

• Amazon Sidewalk, Wireless M-BUS, Wi-SUN FSK, and Z-Wave.

• 
  

• The LoRa2021F33-2G4 is manufactured and tested using strictly lead-free processes and is fully compliant with RoHS and REACH standards.

Electrical Characteristics

Note: For the 2.4GHz LNA (DIO5), it should normally be set to high level (Bypass OFF). If set to low
level, sensitivity will decrease by 12dB (Bypass ON).
