DNT90CA - 900 MHz Frequency Hopping Spread Spectrum Transceiver DNT90PA - Point-to-point, Point-to-multipoint, Peer-to-peer and Store & Forward Capabilities - Transmitter Power Configurable to 40 or 158 mW - Built-in 0 dBi Chip Antenna Low Cost - 100 kbps RF Data Rate - 128-Bit AES Encryption 900 MHz FHSS - Separate Serial Port for Diagnostics Transceiver - Analog and Digital I/O for Sensor Applications - FCC and Canadian IC Certified for Unlicensed Operation Module with I/O 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.
