DS STD-302N-R-869M
UHF Narrow Band Multi Channel Transceiver
STD-302N-R
869MHz
The UHF FM narrow band semi-duplex radio module STD-302N-R 869MHz is suitable for industrial remote control application and telemetry
application operated in 869MHz European harmonized band. Custom made SAW filter and narrow band technique provides reliable data
communication in industrial application where its interference rejection and practical distance range is required. Suitable for feedback
system.
