Product overview

DSSS low power radio transceiver



The STD-502-R 2.4 GHz transceiver uses direct sequence spread spectrum (DSSS) modulation and a true diversity circuit, enabling reliable communications even in the congested 2.4 GHz band.
The STD-502-R complies with the European ETSI EN300440, U.S. FCC Part 15.247, IC RSS-210 standards and Japanese ARIB STD-T66 standard, making it ready for the global market.

Low power consumption and battery operation give the STD-502-R the performance demanded for applications where long range and reliability are required.
The transceiver uses a transparent data interface to enable users to communicate using their own protocols.

The modules can be set easily via the UART interface using dedicated commands.
Circuit Design developed an onboard ASIC containing SS correlator (a key part of spread spectrum communications) instead of relying upon conventional RFICs. This ensures long term supply for industrial applications.
