0dBi DC 3.3V TR6260-S1 40MHz Transmitter Operational Description The 2.4 GHz transmitter up-converts the quadrature baseband signals to the 2.4 GHz RF signal, and drives the antenna with a high powered Complementary Metal Oxide Semiconductor (CMOS) power amplifier. The use of digital calibration further improves the linearity of the power amplifier, enabling state-of-the-art performance of delivering +18.5 dBm of average power for 802.11b transmission and +14 dBm for 802.11n transmission. Additional calibrations are integrated to cancel any imperfections of the radio, such as:

Carrier leakage I/Q phase matching Baseband nonlinearities RF nonlinearities Antenna matching These built-in calibration routines reduce the amount of time and required for product test and make test equipment unnecessary Receiver Operational Description The 2.4 GHz receiver down-converts the 2.4 GHz RF signal to quadrature baseband signals and converts them to the digital domain with 2 high-resolution, high-speed ADCs. To adapt to varying signal channel conditions, RF filters, Automatic Gain Control (AGC), DC offset cancelation circuits and baseband filters are integrated within Wi-Fi Module.
