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 up to 40 kbit/s over distances of 30 meters "in-building" and 120 meters open ground.. The BiM-418-40 Transceiver Module Typical features include: Miniature PCB Mounting module SAW controlled FM transmission at -6dBm ERP. License 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 5.5 Volt supply < 15mA (tx or rx) Half duplex data at up to 40 kbit/s Reliable 30 meter in-building range Direct interface to 5V CMOS logic On board data slicer, supply switches and antenna change over. Fast 1ms power up enable for duty cycle power saving 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 (up to 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).
