ISL3686A
FN8065.1
Direct Down Conversion Transceiver
www.datasheet4u.com
The Intersil ISL3686A is a highly
integrated SiGe process, direct down
conversion transceiver and is part of
the PRISM GT, 2.4GHz 54Mbps, IEEE802.11b/g compliant
radio chipset. The ISL3686A directly interfaces with Intersil’s
ISL3865A Baseband Processor (BBP) and ISL3880
Integrated Medium Access Controller (MAC) with BBP. The
addition of the ISL3980 Intersil power amplifier, and the
ISL3084 5GHz VCO completes the LAN radio application.
