TX1-173.250-10

VHF Narrow Band FM Transmitter

$32.95

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.

Description

Typical features include:

  • CE Certified by independent Notified Body
  • Verified to comply with harmonised radio standard ETSI EN 300 220-3 by accredited Test Laboratory
  • Verified to comply with harmonised 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 to 10 kb/s 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 minimize
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.
