BCM4356 Advance Data Sheet
WLAN Radio Subsystem
Section 12: WLAN Radio Subsystem
The BCM4356 includes an integrated dual-band WLAN RF transceiver that has been optimized for use in
2.4 GHz and 5 GHz Wireless LAN systems. It has been designed to provide low-power, low-cost, and robust
communications for applications operating in the globally available 2.4 GHz unlicensed ISM or 5 GHz U-NII
bands. The transmit and receive sections include all on-chip filtering, mixing, and gain control functions.
Sixteen RF control signals are available (eight per core) to drive external RF switches and support optional
external power amplifiers and low-noise amplifiers for each band. See the reference board schematics for
further details.
A block diagram of the radio subsystem (core 0) is shown in Figure 34 on page 83. Core 1, is identical to Core 0
without the Bluetooth blocks. Note that integrated on-chip baluns (not shown) convert the fully differential
transmit and receive paths to single-ended signal pins.
