I/Q Signal Mismatch Calculator
Amplitude mismatch
dB
Note: This is Q amplitude / I amplitude, converted to dB.
Phase mismatch
°
Note: This is Q phase - (I phase - 90°).
Resulting unwanted signal
dB
Note: This is magnitude of unwanted spectral component (at frequency -f) relative to wanted component (at frequency f), in dB.
