PRODUCT
Brief
BCM2051 802.11B RADIO
BCM2051 FEATURES
• Zero IF, single-chip direct conversion radio integrates
complete 802.11b RF and IF.
• Fully integrated VCO minimizes external component
count and reduces overall BOM cost.
• ^{Single 2.7V to 3.3V voltage supply.}
• ^{Operation over extended temperature range provides}
robust radio performance in integrated laptop and
embedded designs.
• Highly linear receive path ensures robust, interference-
free operation.
• Exceptional adjacent channel and out-of-band blocking
mitigates the effects of other wireless LAN, Bluetooth,
and microwave oven effects.
SUMMARY OF BENEFITS
• Monolithic implementation in a standard digital
CMOS process with minimal external components
provides a manufacturable low-cost 802.11b RF/IF
solution.
• On-chip auto-calibration eliminates process variation
across components and mitigates temperature
variation, enabling it to be used in high-volume
applications.
• Performance is optimized to ensure the robust
performance in real-world operating environments.
• Low power consumption enables integration into low-
power wireless solutions.
• Minimum external BOM provides the lowest cost
solution for 802.11b radio solutions.
