The DNT900 FHSS transceiver module is a low cost, high-power solution for robust wire-
less data communications in the 900 MHz ISM band. The DNT900 RF output power can
be set from 1 mW to 1 W, and the RF data rate can be set from 38.4 to 500 kb/s. The
DNT900 receiver includes a low-noise preamplifier protected by two SAW filters, provid-
ing an excellent combination of receiver sensitivity and out-of-band interference rejection.
The DNT900 module includes analog, digital and serial I/O, providing the flexibility and
versatility to serve applications ranging from cable replacements to sensor networks. The
DNT900 transceiver module is easy to integrate and provides reliable wireless communi-
cations up to 40 miles in line-of-sight installations.
