The transceiver board is a 300 to 960MHz multi-channel transceiver module. This module is designed for general purpose applications, for example in the european bands 433MHz and 868MHz or for similar applications in North America or Asia, e.g. for 315MHz or 915MHz. It is also well-suited for narrow-band applications which meet the ARIB standard STD-T67 in the frequency range 426MHz to 470MHz.
The output power, frequency channel, modulation type and frequency deviation are programmable via the serial programming interface (SPI). The synthesizer operates with a fractional-N PLL and VCO with integrated inductor. The high frequency resolution of the DEL-TRX300-960 and its PLL phase noise performance facilitate it for narrow-band applications.
There are six selectable modulation schemes: on-off keying (OOK), binary frequency shift keying (FSK), minimum shift keying (MSK) as well as their Gaussian filtered versions (GFSK, GMSK, GOOK). The low-IF receiver part comprises fully integrated digital demodulation with autonomous packet recognition and self-polling features for operation in low-power environments.
