UHF Narrowband Multi Channel Transceiver The UHF FM narrowband semi-duplex radio modules available in STD-302Z 1216 and 1252 MHz versions are suitable for industrial remote control and telemetry applications operating in the 1216 and 1252 MHz bands. The SAW filter and narrowband technique provides reliable data communication in industrial applications where interference rejection and practical distance range is required. Suitable for feedback systems. Programmable RF channel Receiver sensitivity -115 dBm Excellent vibration and shock resistance / Mechanical durability FSK narrowband 419 MHz (China) / 429 MHz (Japan) / 434 MHz (EU) / 447 MHz (Korea) / 458 MHz (UK) / 869 MHz (EU) available Applications ■ Industrial remote control system General Parameter Communication method Simplex, Half duplex Emission type Channel step Frequency stability Supply voltage 15 ms typ.
