STD-302Z 1216/1252 MHz

Product catalog summary

Overview
The UHF FM narrowband semi-duplex radio modules, available in STD-302Z 1216 and 1252 MHz versions, are designed for industrial remote control and telemetry applications. They operate in the 1216 and 1252 MHz bands, utilizing a SAW filter and narrowband technique for reliable data communication, interference rejection, and practical distance range. These modules are suitable for feedback systems.
