BiM-UHF
Low Power UHF Data Transceiver Module
UK Version - BiM-418-40
Euro Version - BiM-433-40
The BiM-418-40 and BiM-433-40 are
miniature UHF radio modules
capable of half duplex data
transmission at speeds upto 40 Kbit/s
over distances of 30 metres "in-
building" and 120 metres open ground
Features
Miniature PCB Mounting module
Licence Exempt operation in UK on 418MHz, MPT 1340 (BiM-418-40)
ETS 300-220 tested for European use on 433.92 MHz (BiM-433-40)
SAW controlled FM transmission at -6dBm ERP.
Double conversion Superhet receiver
-107dBm receive sensitivity
Single 4.5 to 5.5V supply < 15mA (tx or rx)
Half duplex data at upto 40 kbit/s
Reliable 30 metre in-building range
Direct interface to 5V CMOS logic
Fast 1ms power up enable for duty cycle power saving
On board data slicer, supply switches and antenna change over.
BiM-UHF transceiver
The module integrates a low power UHF FM transmitter and matching superhet receiver together with
the data recovery and TX/RX change over circuits to provide a low cost solution to implementing a Bi-
directional short range radio data link. The high data rates (upto 40kbit/s) and fast TX/RX changeover
(<1ms) make the BiM transceiver ideal for high integrity one to one links / multi-node packet switch
networks. Rapid RX power up ( <1ms ) allows effective duty cycle power saving of the receiver for
battery powered applications
(e.g. 15µA average @ 1ms ON : 1sec OFF).
Typical applications :-
Medium speed computer networks
Laptop > PC > printer links
High integrity wireless Fire / Security alarms
Building environment control / monitoring
Vehicle alarm systems
Remote meter reading
Authorisation / Access control

Pin Description
pin 1 & 3
RF GND
www.DataSheet4U.com
These pins should be connected to the ground plane against
which the integral antenna radiates . Internally connected to
pins 9,10,18 .
pin 2
Antenna
RF input / RF output for connection to an integral antenna. It
has a nominal RF impedance of 50and is capacitively
isolated from the internal circuit.
pin 9, 10, 18 Vss
0V connection for the modulation and supply
pin 11
CD
Carrier Detect - When the receiver is enabled, a low indicates a
signal above the detection threshold is being received. The
output is high impedance (50k) and should only be used to drive a
CMOS logic input.
pin 12
RXD
This digital output from the internal data slicer is a squared
version of the signal on pin 13 (AF). This signal is used to
drive external digital decoders, it is true data (i.e. as fed to the
transmitters data input). The 10koutput impedance is
suitable for driving CMOS logic.
Note: this output contain squared noise when no signal is
being received.
pin 13
RX Audio
This is the FM demodulator output. It has a standing DC
bias of approximately 1.5V and may be used to drive
analogue data decoders such as modems or DTMF decoders.
Output impedance is 10k. Signal level approx. 0.4V pk to
pk. We recommend this signal always be available on a
convenient test point for diagnostic purposes.
Note: unlike the RXD output which is always true data, this
output is true data on the BiM-418 and inverted on
the BiM-433.
pin 14
TXD
Should be driven directly by a CMOS logic device running on
the same supply voltage as the module. Analogue drive may
be used but must not drive this input above Vcc or below
0V. This input should be held at <0.5V when the TX is
not selected to prevent current leak (see block diagram).
