RXQ1 Applications
The RXQ1 is a dual band ‘transceiver only’ RF module, which has applications in many areas where reliable
half duplex communications are required over ranges up to 200 metres. The crystal controlled narrow band
design gives optimum performance in the 433 MHz band and the dual channel capability allows for the design
of more complex networks than had previously been possible.
