The DNT90 FHSS transceiver module provides a low-cost, versatile solution for wireless data com-
munications 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, digi-
tal 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.
