miniature
capable
UHF
half
radio
modules
data
of
duplex
transmission at speeds upto 40 Kbit/s
over distances of 30 metres "in-
building" and 120 metres open ground
BiM-UHF transceiver
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.
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
