In the project Treufunk, IAS develops a multi-band low power transceiver for industry 4.0 and IoT applications. Particular importance is set to the reliability of communication. Therefore, the possibility to send the data stream in the three ISM frequency bands 433MHz, 800-930MHz, 2.4GHz is implemented. As a result, data transmission is still possible when two of the three bands are disturbed. A sleep mode and a wake-up receiver are also implemented for low current consumption. The on-chip PLL and the integrated LDOs reduce the required external components to a minimum.


The picture shows the block diagram of the entire system. The upper part depicts the receive path. It consists of the Wake Up receiver for the 2.4GHz band, which wakes up the chip out of the sleep mode when a signal is received. Below, the receive path for the data is depicted. The input signals of the three bands are mixed down and converted into a digital signal by a delta sigma converter. The lower part shows the Rx path and the on chip PLL. The data is modulated by a two-point modulation and sent by the three power amplifiers on the respective band.
