Tx mode:
Port 1 impedance: 50Ω
Port 2 and 3 impedance*: Complex conjugate to EFR32 ZIC,TX on
Port 4 and 5 impedance*: Load impedance of EFR32 ZIC,RX off
IL=TX SDS21
RL=TX SSS11 / TX SDD22
Amplitude Difference = dB(S(1,2)/S(1,3))
Phase Balance = Phase(S(1,2)/S(1,3))
Rx mode:
Port 1 impedance: 50Ω
Port 4 and 5 impedance*: Complex conjugate to EFR32 ZIC,RX on
Port 2 and 3 impedance*: Load impedance of EFR32 ZIC,TX off
IL=RX SDS21
RL=RX SSS11 / RX SDD22
Amp_balance = dB(S(1,4)/S(1,5))
Phase_balance = Phase(S(1,4)/S(1,5))
