BiM2A/BiM2H
433MHz Wide Band FM radio transceiver
BiM2A is a half-duplex crystals controlled PLL
wideband FM transceiver operating on 433.05-
434.79MHz European SRD band.
It is an enhanced replacement for the SAW
based BiM2 and has better frequency accuracy
and temperature stability.
BiM2H is a high power version with 25mW RF
power and specifically made available for
Australian/New Zealand users.
Fig. 1: BiM2A-433-64
Features
Data rates up to 64kbps
Crystal controlled PLL FM circuitry for both Tx and Rx
Receiver Sensitivity:
-101dBm for 1ppm BER (64kbps)
-104dBm for 1ppm BER (10kbps)
Supply: 2.9V - 16V @ 14mA TX (10mW), 25mA TX (25mW), 11mA Rx
Usable range up to 300 metres external, 75 metres in building
SAW front end filter and full screening
RSSI (standard) or carrier detect option
Analogue and digital baseband
Low profile with small footprint
33 x 23 x 5mm
Conforms to European EN 301 489-3 and ETSI EN 300 220-3 (ERP @ 10mW)
Conforms to Australian/New Zealand AS/NZS 4268:2003 (ERP @ 25mW)
Instead of the SAW-based technology of the BiM2, the BiM2A and BiM2H use a PLL circuit locked to a
crystal for better frequency stability over a wider temperature range (-20C to +70C) and supply range
(2.9 – 16V), at the expense of slightly slower power-up. The BiM2A is available as standard on
frequencies of 433.92MHz and 434.42MHz.
The BiM2H can be made available if required in an extra-high-power version (BiM2EH), in the same
footprint and pinout but giving 100mW nominal output power at 3.7 - 16V supply with a current
consumption of less than 45mA.
