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.
