WebThis is the difference in amplitude of the available RF signal to the IF signal output (downconverter), or from the IF signal to the RF signal (upconverter). For passive mixers, the conversion gain magnitude is always less than unity, perhaps -5 to -10 dB. WebAlso, any frequency errors in the input signal will be present during filtering. The solution is to: Tolerate this problem (after quantifying its effects). Use an AFC loop which controls the frequency error before downconversion. Don’t use this trick – …
