The DNT90CA and DNT90PA FHSS transceiver modules provides a low-cost, versatile solu-
tion for wireless data communications in the 900 MHz ISM band. The DNT90CA/PA RF out-
put power can be set at 40 or 158 mW. The DNT90CA/PA receiver input is protected by a
low-loss SAW filter, providing an excellent combination of receiver sensitivity and out-of-band
interference rejection. The DNT90CA/PA modules include analog, digital and serial I/O, pro-
viding the flexibility to serve applications ranging from cable replacements to sensor net-
works. The built-in chip antenna makes these modules very easy to integrate.
