Featuring high performance narrowband, blocking and sensitivity, the module is suited for rugged, noisy industrial environments where good channel selectivity is required.
Other standard features include a range of selectable RF power levels (maximum 50mW RF power) and data rates and user data input is transparent allowing the use of proprietary protocol. The STD-601 module is surface mountable, requiring minimal PCB area and is just 5mm high making it suitable for design into portable equipment.
Key specifications of the STD-601 400 MHz include 429, 434, 447 and 458MHz customer selectable frequency bands, selectable RF power outputs of 50, 25, 20, 10, 5 and 1mW, selectable RF bit rates of 1200, 2400, 4800, 9600, 19200bps, asynchronous data input with transparent interface, power consumption 35mA typical (TX 10mW, 3 V), Communication range 600 m (LOS) at 10mW, compact size 20 × 32 × 5 mm SMD
In addition to the STD-601 400 MHz transceiver Circuit Design also manufactures a single band 434MHz version which has CE EN300220 approval with low power consumption of just 26mA (TX 10mW, 3 V).
Evaluation boards for the Circuit Design STD-601 transceiver are available from LPRS for designers to develop and prove their wireless communication systems.
