433 / 868MHz FM Data Transceiver
The BIM2/3G data radio module is a PLL
synthesiser based miniature PCB
mounting UHF radio transceiver which
enable the simple implementation of a
wireless data link at up to 128 kbps at
distances up to 75 metres in-building
and 300 metres open ground.
Features

!
Data rates up to 128 kbps
Figure 1: BIM3G-869-64-5V
Usable range up to 300 m
Versions available on 433.92MHz, 434.42MHz and 868MHz band
Fully screened
Low profile with small footprint
Designed for compliance with EN 300 220-3 (radio) and EN 301 489-3 (EMC) standards
!
!
Available for operation at 433.92MHz, 434.42MHz and 868MHz band in the UK and Europe, these modules
combine full screening with extensive internal filtering to ensure EMC compliance by minimising spurious
radiations and susceptibilities. The BIM2/3G module will suit one-to-one and multi-node wireless links in
applications. Because of their small size and low power requirements, the module is ideal for use in portable,
battery-powered applications such as hand-held terminals.
