BiM3A
869/914MHz high speed FM radio transceiver module
The BiM3A radio transceiver module is
similar in size and pinout to the BiM2,
offering all the advantages of the latter but
with reduced power consumption and
antenna size. The BiM3A replaces the
obsolete BiM3.
The BiM3A suited to battery-powered
portable and handheld equipment
requiring a high degree of miniaturisation.
Two frequency variants are available as
standard to suit applications in Europe or
North America.

Features
CE certified by independent Notified Body
EU version to harmonised standards EN 300 220 and EN 301 489
North American version to FCC Part 15.249 and RSS-210
Usable range up to 200 metres external, 50 metres in building
Data rates up to 64kbps
Crystal controlled PLL FM circuitry for both Tx and Rx
SAW front end filter and full screening
Low profile with small footprint
Low power requirements: 2.7V - 6V @ typically 8mA Tx, 11mA Rx
The BiM3A is a half duplex radio transceiver module for use in bidirectional data transfer applications
at ranges up to 200 metres. Two frequency variants are available for licence-exempt operation in either
the European 868-870MHz or North American 902-928MHz bands. Internal voltage regulation is
incorporated allowing operation from DC supplies of 2.7V to 6V.
The small footprint of 33 x 23mm and low profile of 5mm facilitate convenient integration onto a
motherboard. The raw data rate capability of 64kbps supports high data throughput in ‘streaming’
applications, or alternatively allows efficient airtime utilisation in multi-node scanning networks.
