Figure shows a pair of tuned circuits. The capacitor unit is the variable voltage capacitor diode or varactor VFO circuit. Diode display equivalent of junction capacitance for its upon reverse bias. Thus, the frequency of the oscillator circuit can be controlled by the tuning voltage Vt. NE-602 is a RF chip with good performance. It can be used in a variety of receivers, converters, oscillators, signal generators and other equipment. figure: Voltage-tuned NE-602 oscillator circuit
