TDA6650ATT; TDA6651ATT
5 V mixer/oscillator and low noise PLL synthesizer
Vo =Vmeas + 3.75 dB.
V’meas =Vo (transformer ratio N1/N2 = 5 and loss).
Wanted signal source at fRFpix is 80 dBV.
Unwanted output signal at fsnd.
The level of unwanted signal is measured by causing 0.3 % AM modulation in the wanted signal.
N1 = 10 turns.
N2 = 2 turns.
N1/N2 = 5.
