The Aurora BTE power radio model contains two radio transceivers running at 3.84 MHz and 2.4 GHz and both implemented on a single hardware platform.
The radio model is implemented in an engine module mounted on the
main PCB with connections to the antennas, the microphones, the 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, and inductive radio
transceiver 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)
transceiver using GFSK modulation with 1 Mbit/s data rate also capable
of proprietary modes with higher data rates and connected to a short PCB

Below the main flex PCB of the Aurora BTE power radio model with the most important electrical and electro-mechanical components can be seen:
The most important part of the radio model is the Engine Module mounted on the main flex PCB, which connects it to both the EEPROM memory and all external
connections: On the top side, these are the microphones, the battery terminals, the external connector and the push button.
The Aurora BTE power radio model requires only a single cell battery and an external speaker to be attached and plastic shells, defining the industrial design
of a hearing aid end product and holding everything together, in order to be operational.
