This paper describes the design of the RF front-end, currently implemented as a part of a long-range UHF radio transceiver. The project aims to condition the commercial WiFi HaLow (IEEE 802.11ah) signal to fit in the desired frequency band and enable communication for longer distances. Assumptions of the design, described at the beginning, are followed by a more detailed description of subsequent hardware functional blocks that handle data transmission.
