BCM43143 Advance Data Sheet
Single-Band Radio Transceiver
Single-Band Radio Transceiver
The BCM43143 has a 2.4 GHz radio transceiver that ensures low power consumption and robust
communication in 20 MHz and 40 MHz channel bandwidths as specified in IEEE 802.11n.
Receiver Path
The BCM43143 has 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. 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. Linear on-chip power amplifiers are
included, which are capable of delivering a nominal output power exceeding +15 dBm while meeting the IEEE
802.11n specification. The TX gain has 128 steps of 0.25 dB per step.
Calibration
The BCM43143 features 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. These calibration routines are performed periodically in the course of normal radio operation.
