DBPSK, DQPSK, CCK, and MBOK • Supports Full or Half Duplex Operations • On-Chip A/D Converters for I/Q Data (3-Bit, 22 MSPS) and RSSI (6-Bit) • Backwards Compatible with HFA3824A, HFA3860A • Supports Dual Antenna Diversity The HFA3860B has on-board A/Ds for analog I and Q inputs, for which the HFA3724/6 IF QMODEM is recommended.
Differential phase shift keying modulation schemes DBPSK and DQPSK, with data scrambling capability, are available along with Complementary Code Keying and M-Ary Bi-Orthogonal Keying to provide a variety of data rates.
Builtin flexibility allows the HFA3860B to be configured through a general purpose control bus, for a range of applications.
A Receive Signal Strength Indicator (RSSI) monitoring function with on-board 6-bit A/D provides Clear Channel Assessment (CCA) to avoid data collisions and optimize network throughput.
The HFA3860B is housed in a thin plastic quad flat package (TQFP) suitable for PCMCIA board applications.
