(SSB Conversion Loss)|
In most applications, only one of the signals (fRF+fLO) or (fRF-fLO)
appearing at the IF port of a mixer is of interest; therefore, only one of
these signals (or sidebands) is considered when determining conversion
loss in regard to mixers. Single sideband conversion loss is 3 dB higher
than the conversion loss when both sidebands are considered (double
sideband conversion loss).
