BiM1, TX1H
VHF Narrow Band FM transceiver
The BiM1 transceiver modules offer a
100mW RF output VHF data link in
Radiometrix transceiver standard
pin-out and footprint. This makes the
BiM1 ideally suited to those low
power applications where existing
wideband
transceivers
provide
insufficient range.

Conforms to EN 300 220-3 and EN 301 489-3 (10mW version only)
Standard frequency 151.300MHz
Other frequencies from 120MHz to 180MHz
Available separately as BiM1T transmitter and BiM1R receiver
TX1H is a BiM1T in TX1 pin-out
Data rates up to 10kbps for standard module
Usable range over 10km
Fully screened
Feature-rich interface (RSSI, analogue and digital baseband
Low power requirements

The BiM1 is a half duplex radio transceiver module for use in long range bi-directional data transfer
applications at ranges up to 10kilometres. The module operates on the UK licence exempt frequency of
173.225/173.250MHz with 10mW RF output and Australian frequency of 151.300MHz with 100mW RF
output. The small footprint of 23 x 33mm and low profile of 10mm together with low power
requirements of <80mA (for 100mW) at 3.8V enables convenient PCB installation. BiM1 is also
available as separate BiM1T transmitter and BiM1R receiver which can be used as dual-in-line
equivalents of TX1 transmitter and RX1 receiver respectively.
