BCM43236/BCM43236B Preliminary Data Sheet
Dual-Band Radio Transceiver
Dual-Band Radio Transceiver
Integrated into the BCM43236/BCM43236B chips is Broadcom's world-class dual-band radio transceiver that
ensures low power consumption and robust communications for low-cost applications operating in the 2.4 GHz
and 5 GHz bands. Channel bandwidths of 20 MHz and 40 MHz are supported as specified in IEEE 802.11n.
Receiver Path
The BCM43236/BCM43236B chips have a wide dynamic range, direct conversion receiver. It employs high order
on-chip channel filtering to ensure reliable operation in the noisy 2.4 GHz ISM band or the entire 5 GHz U-NII
band. The excellent noise figure of the receiver makes an external LNA unnecessary.
Transmitter Path
Baseband data is modulated and upconverted to the 2.4 GHz ISM band or the 5 GHz U-NII bands, respectively.
Linear on-chip Power Amplifiers are included, which are capable of delivering a nominal output power
exceeding +15 dBm while meeting the IEEE 802.11a and 802.11g specifications. The TX gain has a 78 dB range
with a resolution of 0.25 dB.
Calibration
The BCM43236/BCM43236B chips feature dynamic on-chip calibration, eliminating process variation across
components. This enables the device to be used in high-volume applications because calibration routines are
not required during manufacturing testing. These calibration routines are performed periodically in the course
of normal radio operation.
