Description of the product
The SATELLINE-M3-TR8 and SATELLINE-M3-TR9 are UHF radio transceiver modules, which
transmit and receive data from the UHF frequency band. The modules are designed to be as
compact and power efficient as possible. They have been developed to be especially suitable for
integration into battery powered and space constrained host applications benefiting from UHF
communications.
The module transmits and receives data via the Air interface, modulates and demodulates,
encodes and decodes the data and sends the received data payload to the DTE port. The DTE
interface is used to provide power and communicate with the module.
