BiM2/BiM3G
Issue 2, 7 March 2013
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-869.85-64-5V
Usable range up to 300 m
Versions available on 433.92MHz, 434.42MHz, 868.30 or 869.85MHz
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 433.05-434.79MHz, 868-870MHz 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.
Applications
Data loggers
EPOS equipment, barcode scanners, belt clip printers
Audience response systems
In-building environmental monitoring and control
Security and fire alarms
Restaurant ordering systems
Vehicle data up/download
