The PA AU5 MiniBTE M radio model (PA_AU5_MBTE_M) contains two radio transceivers running at 3.84 MHz and
2.4 GHz and both implemented on a single hardware platform.
Additionally, a full featured RFID tag (IC2) capable of receiving signals at 865 MHz – 928 MHz. The RFID tag has no
electrical/galvanic connections related to the rest of the PCB in PA AU5 MiniBTE M and are passive.
The radio model is implemented in an engine module mounted on the main PCB with connection to the antennas,
telecoil, the microphones, the internal speaker and the battery terminals. The radio model can be seen in 3D overview
to the left.
The 3.84 MHz radio is a low power, short range inductive radio transceiver ( N F M I – N e a r F i e l d m ag n e t i c
I n d u c t i o n ) working at a single channel at 3.84 MHz using MSK modulation with 320 kbit/s data rate and
connected to a small coil antenna.
The 2.4 GHz radio is a Bluetooth Low Energy (BLE core 5.0) transceiver using GFSK/2FSK modulation with 1
Mbit/s, 2 Mbit/s data rate also capable of proprietary reception modes (xBLE) with higher data rates (2 Mbit/s, 4
Mbit/s) using 2FSK/4FSK modulation. The 2.4 GHz radio is connected to a short wire antenna with a proprietary
antenna connector.
