BCM43362 Data Sheet
WLAN Radio Subsystem
Section 6: WLAN Radio Subsystem
The BCM43362 includes an integrated WLAN RF transceiver that has been optimized for use in 2.4 GHz
Wireless LAN systems. It is designed to provide low power, low cost, and robust communications for
applications operating in the globally available 2.4 GHz unlicensed ISM band. The transmit and receive sections
include all on-chip filtering, mixing, and gain control functions. Improvements to the radio design include shared
Tx/Rx baseband filters and high immunity to supply noise.
