HX1 (300mW)
VHF Narrow Band FM 300
m
W Transmitter
The special HX1 transmitter modules
offer a 300mW RF output VHF data
link in Radiometrix SIL standard pin-
out and footprint. This makes the HX1
ideally suited to those low power
applications where existing narrow
band and wideband transmitters
provide insufficient range. Together
with the matching NRX1 or BiM1R
receiver a one-way radio data link can
be achieved over a distance up to
10km+ with suitable choice of data
rate and antennas.

Low power requirements
The HX1 is a narrow band radio transmitter module for use in long range data transfer applications at
ranges up to 10kilometres. HX1 transmitter circuit is the BiM1T transmitter circuit in the TX1 pin-out
with slightly enlarged dimension to accommodate extra Power Amplifier circuit to produce 300mW RF
output and available for operation on 169MHz European licence exempt frequency band.
