GENERAL DESCRIPTION & FEATURES
General Description
The UHF FM narrow band semi-duplex radio data module STD-302N-R is an STD-T67 compliant,
high performance transceiver designed for use in industrial applications requiring long range, high
performance and reliability.
All high frequency circuits are enclosed inside a robust housing to provide superior resistance
against shock and vibration. A narrow band technique enables high interference rejection and
concurrent operation with multiple modules.
STD-302N-R 429MHz, a narrowband module with 12.5 kHz channel steps, achieves high TX/RX
switching speed, making it an ideal RF unit for inclusion in feedback systems.
This product is designed to meet the basic specifications of the standard, however it has not been
certified for conformity with the technical regulations. Users are required to perform the
procedures for certification with their final products after installing this product in their systems.
