Product description:

The transceiver module is a complete and efficient RF transceiver, suited for exchanging data with a data rate up to 300 kbit/s.Because of the SMD construction, the module has a very small shape.
The module can be controlled directly by a microcontroller with SPI interface. This way the total hardware of the system can be limited to a minimum.

* under specific conditions:
The range depends on the following parameters:

- TX power
- RX sensitivity
- Data rate
- Spreading Factor
- Transmitter bandwidth
- Receiver bandwidth
- Antenna height
- Antenna type
- Radio protocol
- Etc.

** Using 2 modules of the same type and a data rate of 146 bps (LoRatm).

*** the LoRatm modem specification can be extended with a TCXO (temperature compensated oscillator) and the calibration of the center frequency. When using a TCXO, the specifications are:

- Bandwidth: 7.8 kHz tot 500 kHz
- Effectieve Bitrate: 9 bps - 37.5 kbps
- Sensitivity: -111 dBm tot -148 dBm
- Maximum Link-budget: 168 dB
- Range > 10 kilometer

The maximum Link-budget can be reached with maximum transmit power, a bandwidth of 7.8 kHz, a Spreading Factor of 12 and a Coding Rate (FEC) of 4/5. The effectieve bitrate is 9.14 bits/s.
