Radiometrix Hartcran House, 231 Kenton Lane, Harrow, HA3 8RP, England IssueVHF October 2005 FM Data Transmitter and Receiver Modules RX1 2, 17 Narrow Band TX1 & Tel: +44 (0) 20 8909 9595, Fax: +44 (0) 20 8909 2233 VHF Narrow Band FM Transmitter and Receiver The TX1 and RX1 form a miniature VHF radio transmitter/receiver pair designed for PCB mounting and suitable for extended range data links at speeds up to 10kbps. Link ranges of 10km+ are achievable with suitable choice of data rate and antennas. Features: left: TX1 transmitter right:RX1receiver CE Certified by independent Notified Body Verified to comply with harmonised radio standard ETSI EN 300 220-3 and EMC standard ETSI EN 301 489-3 by accredited Test Laboratory Frequencies available as standard: 173.225MHz, 173.250MHz Other frequencies from 151.300MHz to 173.250MHz available to order Data rates up to 10 kbps with 25kHz channel spacing Usable range to 10km+ Screened construction Available for licence-exempt operation in the UK 173MHz bands, the TX1 & RX1 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, both modules are ideal for use in battery-powered portable applications such as hand-held terminals.

The end-fed half wave is the same length as the dipole but consists of a single rod or whip fed at the bottom via a matching network. Mounting options are similar to those for the quarter-wave whip. A ground plane is sometimes used but is not essential. The end-fed arrangement is often preferred over the centre-fed dipole because it is easier to mount in the clear and above surrounding obstructions. Yagi. This antenna consists of two or more elements mounted parallel to each other on a central boom. It is directional and exhibits gain but tends to be large and unwieldy – for these reasons the yagi is the ideal choice for links over fixed paths where maximum range is desired. Please note: Using a Yagi or other gain antenna with the TX1 will exceed the maximum radiated power permitted by UK type approval regulations. It can be used in the UK only in conjunction with the RX1 receiver. For best range in UK fixed link applications use a half-wave antenna on transmit and a half-wave or Yagi on receive, both mounted as high as possible and clear of obstructions. The above antennas may be obtained from several sources in the UK, for example: R W Badland Ltd Unit 3 Providence Street Lye Stourbridge West Midlands DY9 8HN England Tel. +44 (0)1384 423160 Fax +44 (0)1384 423958 / 895051 info@badland.co.uk www.badland.co.uk Renair Antennae Ltd. 11-15 Chase Road Park Royal London NW10 6PT England Tel: +44 (0)20 8965 3001 Fax: +44 (0)20 8965 5773 sales@renair.co.uk www.renair.co.uk Radiometrix Ltd., TX1 & RX1 Data Sheet page 13 Module mounting considerations The modules may be mounted vertically or bent horizontal to the motherboard. Note that the four components mounted on the underside of the RX1 are relatively fragile – avoid direct mechanical contact between these and other parts of the equipment if possible, particularly in situations where extreme mechanical stresses could routinely occur (as a result of equipment being dropped onto the floor, etc). Good RF layout practice should be observed. If the connection between module and antenna is more than about 20mm long use 50Ω microstrip line or coax or a combination of both. It is desirable (but not essential) to fill all unused PCB area around the module with ground plane. Variants and ordering information The TX1 transmitter and RX1 receiver are manufactured in the following variants as standard: For alarm applications on 173.225MHz: TX1-173.225-10 RX1-173.225-10 Transmitter Receiver For general applications on 173.250MHz: TX1-173.250-10 RX1-173.250-10 Transmitter Receiver Other variants can be supplied to individual customer requirements at frequencies from 151.300MHz to 173.250MHz and/or optimised for specific data speeds and formats.
