EW N Issue 1, 27April 2007 Radiometrix Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233 NRX1 Low cost VHF Narrow Band FM receiver The NRX1 is a VHF radio data receiver and it offers a low power, reliable data link in a Radiometrix SIL standard pin out and footprint. It is an enhanced, low cost version of the Radiometrix RX1, but in a slightly larger dimension. NRX1 is compatible with the TX1 series of transmitters, and the BiM1 transceiver. Figure 1: NRX1-173.250-10 Features Designed to comply with harmonised radio standard EN 300 220-3 and EMC standard EN 301 489-3 Frequencies available as standard: 151.3000MHz, 169.4125MHz, 173.2250MHz and 173.2500MHz Other custom frequencies from 120MHz to 180MHz available to order Data rates up to 10 kbps with 25kHz channel spacing Usable range to 10km+ with matching transmitter Fully screened NRX1 is a VHF equivalent of Radiometrix UHF NRX2 receiver and it is available for licenceexempt operation in the UK 173MHz bands and European 169MHz band. It is also available in the Australian frequency of 151.300MHz. NRX1 modules combine effective screening with internal filtering to minimise spurious radiation and susceptibility thereby ensuring EMC compliance. They 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. Because of their small size and low power consumption, these modules are ideal for use in battery-powered portable applications such as handheld terminals.
