DBPSK, DQPSK, and MBOK • Supports Full or Half Duplex Operations • On-Chip A/D Converters for I/Q Data (3-Bit, 22MSPS) and RSSI (6-Bit) • Backwards Compatible with HFA3860 • Supports Antenna Diversity The HFA3860A 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 M-Ary Bi-Orthogonal Keying to provide a variety of data rates.
Built-in flexibility allows the HFA3860A 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 HFA3860A is housed in a thin plastic quad flat package (TQFP) suitable for PCMCIA board applications.
Applications • Enterprise WLAN Systems • Systems Targeting Ethernet Data Rates • DSSS PCMCIA Wireless Transceiver • Spread Spectrum WLAN RF Modems • TDMA Packet Protocol Radios • Part 15 Compliant Radio Links • Portable Bar Code Scanners/POS Terminal • Portable PDA/Notebook Computer Ordering Information PART NO.
