DD = tone at 1kHz and -5dBm0
measured_result = (tone level on DD) - (tone level
onDU)
multitone applied on RAC of amplitude 100mVp
and measure performed on Vout
where F(s) is the ideal transfer function
(RAC/Vout) from simulation
F(m) is the measured transfer function
COFISLIC return loss
----------------
F(s) + F(m)
F(s) - F(m)
