1 The maximum gain is defined as PRF, Exp./PI or PRF, Exp./PQ.
2 This is limited by the amplifier and not by the IQ mixer.
3 The LO isolation is defined as PLO, input/PLO, Exp. in RF mode.
4 SW1 is the RF switch for the RF or the LO signal that goes to the Exp. output port.
5 SW2 is the RF switch for the RF signal that goes to the Calib. or to the Exp. output port.
