Receiving ADS-B With a Semtech LR2021 LoRa Chip (opens in new tab)

Over on his blog, Zoltán Papp and team have created an interesting write-up investigating whether Semtech's LR2021, one of the latest LoRa transceiver chips, which draws only 10.4 mA at 3.3V, can be used as a single-chip ADS-B receiver at 1090 MHz. The LR2021 natively supports OOK modulation, and the datasheet even hints at ADS-B reception. Building on prior work, the team captured live ADS-B signals with an SDR and replayed them into the LR2021 eval board for repeatable bench testing. The in...
