Description
The RXQ1 / TRXQ1 radio transceiver modules provide reliable wireless communications for the transfer of
data at rates of up to 20 K baud. Their unique features of narrow band operation and user channel selection
combined with excellent interference rejection make them an ideal choice for next generation applications.
Operating within the 433.92MHz band the modules can operate in two narrow band channels; 433.92 MHz
and 434.33MHz. The modules use a crystal controlled design which provides narrow band performance which
is far superior to other wideband ‘SAW’ based designs.
The TRXQ1 Smart Radio Transceiver has the functions of a complete radio modem, it simply requires
CMOS/TTL data at the transmit input and the corresponding transceiver(s) output the same data
There RXQ1 provides a basic Radio transceiver.
Possible applications include one-to-one and multi-node wireless links in applications including car and
building security, EPOS, inventory tracking, remote industrial process monitoring and computer networking.
Because of their small size and low power requirements, both modules are ideal for use in portable, battery-
powered applications such as hand-held terminals.
