HFA3861B
Direct Sequence Spread Spectrum
Baseband Processor
The Intersil HFA3861B Direct
Sequence Spread Spectrum (DSSS)
baseband processor is part of the
PRISM 2.4GHz WLAN Chip Set, and
contains all the functions necessary for
a full or half duplex packet baseband transceiver.
The HFA3861B has on-board A/D’s and D/A 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 HFA3861B 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 HFA3861B is housed in a thin plastic quad
flat package (TQFP) suitable for PCMCIA board
applications.
