BCM43362 Data Sheet
Receive Path
Receive Path
The BCM43362 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.
Transmit Path
Baseband data is modulated and upconverted to the 2.4 GHz ISM band. A linear on-chip power amplifier is
included, which is capable of delivering high output powers while meeting IEEE 802.11b/g/n specifications
without the need for an external PA. This PA can be powered directly from VBAT, thereby eliminating the need
for a separate PALDO. Closed-loop output power control is completely integrated.
Calibration
The BCM43362 features dynamic on-chip calibration, eliminating process variation across components. This
enables the BCM43362 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. Examples of this automatic calibration are baseband filter calibration for optimum transmit and
receive performance and LOFT calibration for leakage reduction. In addition, I/Q Calibration, R Calibration, and
VCO Calibration are performed on-chip.
