BiM3B
869MHz Wide Band FM Radio Transceiver
The BiM3B radio transceiver module is an enhanced high power replacement for the European version BiM3A-869-64.
The BiM3B suited to battery-powered portable and handheld equipment requiring a high degree of miniaturisation.
Two frequency variants are available in the European unlicensed band, one with 5mW RF power with no duty cycle restriction other with 25mW RF power with 1% duty cycle restriction.
The small footprint of 33 x 23mm and low profile of 5mm facilitate convenient integration onto a motherboard. The raw data rate capability of 64kbps supports high data throughput in ‘streaming’ applications, or alternatively allows efficient airtime utilisation in multi-node scanning networks.
The BiM3B is now superseded by BiM3C transceiver.
