The STD-503 2.4 GHz radio transceiver module is suitable for worldwide implementation and targets industrial applications that must have stable and reliable communication for up to 300 yards with battery operation. The module uses noise-resistant direct-sequence spread spectrum (DSSS) modulation, as well as a true diversity receiver design that employs two antennas.
The 1.6 x 1.15 x 0.22 inch module allows switching between up to 20 frequency channels via pin selection or commands. Transmitting at up to 19.2 kps takes 65 ma from a 3.3 V supply. Output power is 10 mW and the device is certified to FCC Part 15.247, EN 300 440, ARIB STD-T66. It operates over -20° to +65°C. $108 ea/single qty.
