The DNT90CA/PA FHSS transceiver modules provides a low-cost, versatile solution for wire-
less data communications in the 900 MHz ISM band. The DNT90CA/PA RF output power can
be set at 40 or 158 mW. The DNT90CA/PA receiver input is protected by low-loss SAW filter,
providing an excellent combination of receiver sensitivity and out-of-band interference rejec-
tion. The DNT90CA/PA modules include analog, digital and serial I/O, providing the flexibility
to serve applications ranging from cable replacements to sensor networks. The built-in chip
antenna makes these modules very easy to integrate.
