DBPSK, DQPSK, and CCK • Supports Full or Half Duplex Operations • On-Chip A/D and D/A Converters for I/Q Data (6-Bit, 22MSPS), AGC, and Adaptive Power Control (7-Bit) • Targeted for Multipath Delay Spreads ~100ns • Supports Short Preamble Acquisition The HFA3861 has on-board A/D’s for analog I and Q inputs and outputs, for which the HFA3783 IF QMODEM is recommended.
Differential phase shift keying modulation schemes DBPSK and DQPSK, with data scrambling capability, are available along with Complementary Code Keying to provide a variety of data rates.
Built-in flexibility allows the HFA3861 to be configured through a general purpose control bus, for a range of applications.
Both Receive and Transmit AGC functions with 7-bit AGC control obtain maximum performance in the analog portions of the transceiver.
The HFA3861 is housed in a thin plastic quad flat package (TQFP) suitable for PCMCIA board applications.
