Product Description
The RF3000 is a monolithic CMOS baseband processor.
It is suitable for use in 11Mbps IEEE802.11b wireless
LAN systems, and contains all functions required to con-
vert a spread-spectrum signal to bit stream. The on-chip
equalizer provides protection against multi-path in high
data rate modes. All functions are configurable via an SPI
port. A complete 2.4GHz radio reference design is avail-
able from RFMD.
