General Description
The UHF FM narrow band semi-duplex radio data module STD-302N-R 458 MHz is a RoHS
compliant, high performance transceiver designed for use in industrial applications requiring long
range, high performance and reliability.
The module is designed to meet the requirements of the R&TTE Directive and to be used in the
458MHz band allocated for Short Range Devices in the UK. The applicable technical standard is
EN 300 220.
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, a narrowband module with 25 kHz channel steps, achieves high TX/RX switching
speed, making it an ideal RF unit for inclusion in feedback systems.
Features
10 mW RF power, 3.0 V operation
Programmable RF channel
Fast TX/RX switching time
High sensitivity -119 dBm
Excellent mechanical durability, high vibration & shock resistance
RoHS compliance
EN 300 220 / EN 301 489 compliant
