The DNT90 FHSS transceiver module provides a low-cost, versatile solution for wireless data communications in the 900 MHz ISM band. The DNT90 RF output power can be set at 40 or 158 mW.
The DNT90 receiver input is protected by low-loss SAW filter, providing an excellent combination of
receiver sensitivity and out-of-band interference rejection. The DNT90 module includes analog, digital and serial I/O, providing the flexibility to serve applications ranging from cable replacements to
sensor networks. The DNT90 transceiver module is easy to integrate and provides reliable wireless
communications up to 5 miles in line-of-sight installations.
