Wanted output signal at fRFW = 367.25 (801.25) MHz; Vo(w) = 100 dBµV.
Measuring the level of the unwanted output signal Vo(u) causing 0.5% AM modulation in the wanted output signal; fRFU = 371.25 (805.75) MHz.
fOSC = 413 (847) MHz.
Filter characteristics: fC = 45.75 MHz, fâ3 dB(BW) = 1.4 MHz, fâ30 dB(BW) = 3.1 MHz.
