(1) Reference state: Tuning attenuator state = 1 / Fine attenuator state = 0 /
Phase shifter state = 0
(2) Noise Figure value for Tuning attenuator state = 0 / Fine attenuator state = 0 /
Phase shifter state = 0
(3) In this mode, the MFC presents a matched load on the RF access pad RXin/TXout
(4) Low influence of cross-talking between phase shifter and fine attenuator
(5) This function allows to adjust roughly the linear gain
(6) Each Amplifiers of Rx and Tx paths can be switched off thanks to separate biasing pads (c.f.
pad allocation table)
(7) Tx linear mode
(8) Tx saturated mode
