TX1 & RX1  
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.

right:RX1receiver  
Features:  
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.
