Double conversion Superhet receiver -107d Bm receive sensitivity Single 4.5 to 5.5V supply < 15m A (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 Bidirectional short range radio data link. The high data rates (upto 40kbit/s) and fast TX/RX changeover (<1ms) make the Bi M 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).
