Please refer to section 7.5.3 of this document for the optimized matching arrangement for each frequency band.
3.3.8. Common Input and Output Front-End
The receiver and the transmitter share the same RFIO pin (pin 32). Figure 13 below shows the configuration of the
common RF front-end.
In transmit mode, the PA and the PA regulator are active, with the voltage on the VR_PA pin equal to the
nominal voltage of the regulator (1.8 V). The external inductance is used to bias the PA.
In receive mode, both PA and PA regulator are off and VR_PA is tied to ground. The external inductance LT1
is then used to bias the LNA.
