nnnn

The DNT900 FHSS transceiver module is a low cost, high-power solution for robust wire-

nnnn

less data communications in the 900 MHz ISM band. The DNT900 RF output power can

nnnn

be set from 1 mW to 1 W, and the RF data rate can be set from 38.4 to 500 kb/s. The

nnnn

DNT900 receiver includes a low-noise preamplifier protected by two SAW filters, provid-

nnnn

ing an excellent combination of receiver sensitivity and out-of-band interference rejection.

nnnn

The DNT900 module includes analog, digital and serial I/O, providing the flexibility and

nnnn

versatility to serve applications ranging from cable replacements to sensor networks. The

nnnn

DNT900 transceiver module is easy to integrate and provides reliable wireless communi-

nnnn

cations up to 40 miles in line-of-sight installations.
