tuning diode a special type of semicon- ductor diode that exhibits a significant change in junction capacitance as the dc potential across the junction is varied. A varactor is a type of tuning diode. ing of the variable capacitor must be to pre- vent voltage from arcing across the capacitor plates. In circuits where high RF power is
