3.3 Receive Mode
In receive mode, antenna diversity is supported. The single ended output of the TR switch is connected
to the RF LNA input through a matching network. Filtering and amplification is all performed by the
radio transceiver. The gain setting is controlled by the BB. The analog IQ outputs are sampled by the
BB by its integrated 22 Msps dual channel 8bit ADC. This received data is demodulated and fed to the
audio processing engine controlling the I2S connections.
