The TX1 & RX1 Data Sheet from Radiometrix Ltd. introduces the features and characteristics of VHF Narrow Band FM Data Transmitter and Receiver Modules. These modules are CE certified by an independent notified body and verified to comply with harmonized radio standard ETSI EN 300 220-3 and EMC standard ETSI EN 301 489-3 by an accredited test laboratory. Standard frequencies available are 173.225MHz and 173.250MHz, with other frequencies from 151.300MHz to 173.250MHz available to order. The modules support data rates up to 10 kbps with 25kHz channel spacing. They have screened construction and internal filtering to minimize spurious radiation and susceptibility, ensuring EMC compliance. The TX1 & RX1 modules are particularly suitable for one-to-one and multi-node wireless links where longer ranges are required at low to moderate data rates. Applications include building security, EPOS and inventory tracking, remote industrial process monitoring, and data networks. Due to their small size and low power consumption, both modules are ideal for use in battery-powered portable applications such as hand-held terminals.
