BiM3H
transceiver
UHF FM 400mW transceiver module
The BIM3H is a miniature PCB mounting
UHF radio data transceiver incorporating a
received signal strength indicator (RSSI). It
allows the simple implementation of data
links at speeds up to 10kbps and
distances up 5000 metres over open
ground.

Features
Figure 1: BiM3H-869.50-10
Designed to comply with harmonised radio standard EN 300 220-3
Designed to comply with harmonised EMC standard EN 301 489-3
Data rates up to 10kb/s
Usable range up to 5000m
Frequency 869.50MHz
Fully screened
Fast data settling time
Available for operation at 869.50MHz in the UK and Europe, the BiM3H combines full screening
with internal filtering to ensure EMC compliance by minimising spurious radiation and
susceptibility. The module suits one-to-one and multi-node wireless links in applications including
car and building security, EPOS and inventory tracking, remote industrial process monitoring and
computer networking. Because of the small size and low power requirements, the BIM3H is ideal
for use in portable, battery-powered applications such as hand-held terminals.
