Description

  The Intersil HFA3861A Direct Sequence Spread Spectrum (DSSS) baseband processor is part of the PRISM® 2.4GHz radio chipset, and contains all the functions necessary for a full or half duplex packet baseband transceiver.The HFA3861A 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 HFA3861A 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 HFA3861A is housed in a thin plastic quad flat package (TQFP) suitable for PCMCIA board applications.
