... The VCO operates at twice the carrier frequency. Its output signal is applied to a frequency divider (divide-by-2) to produce the two LO signals which are 90 degrees out of phase. The VCO is powered from the internal voltage stabilizer to ensure good shift performance. 4 Objective specification TDA8040T out 14 V CC(V) ...
