DS STD-302S-869
UHF Narrow Band Multi Channel Transceiver
STD-302S
869MHz
The UHF FM narrow band semi-duplex radio module STD-302S 869MHz is suitable for industrial remote control application and telemetry
application operated in 869MHz ISM band. SAW filter and narrow band technique provides reliable data communication in industrial
applications where interference rejection and practical distance range is required. Suitable for feedback systems.
