Wanted output signal at fRFW: Vow = 108 dBµV, Vmeas = 92.6 dBµV. We measure the level of the unwanted output signal Vou causing 0.3% AM modulation in the wanted output signal. Vou = Vmeas + 15.4 dB. fRFU = fRFW + 5.5 MHz; fosc = fRF + 38.9 MHz. Filter characteristics: fc = 38.9 MHz; f−3dBBW = 1.2 MHz; f−30dBBW = 2.64 MHz.
