RX1-151.300-10

Manufacturer Part Number
RX1-151.300-10
Description
VHF Narrow Band FM High Power TX
Manufacturer
RADIOMETRIX [Radiometrix Ltd]
Datasheet
The TX1H transmitter modules offer a
100mW RF output VHF data link in
Radiometrix SIL standard pin-out and
footprint. This makes the TX1H ideally
suited to those low power applications
where
wideband
insufficient range. Together with the
matching RX1 or BiM1R receiver a one-
way radio data link can be achieved
over a distance up to 10km+ with
suitable
antennas.
Issue 1, 26 October 2004
Features
The TX1H is a narrow band radio transmitter module for use in long range data transfer applications
at ranges up to 10kilometres.
TX1 pin-out with slightly enlarged dimension to accommodate extra Power Amplifier circuit to
produce 100mW RF output and
