SPREAD-SPECTRUM BASEBAND MODEM
• IEEE802.11b Wireless LAN Systems
• ISM Band Systems
• Direct Sequence Systems
• Wireless Modems
• Wireless Point-to-Point
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.
• On-Chip ADCs and DACs, RSSI, AGC
• BPSK/QPSK/CCK
• 250nS Delay Spread Equalizer
• Supports Antenna Diversity
• Reference Design Available
