Varactor-Tuned Oscillators

Description HP VTO-8000 Series oscillators use a silicon transistor chip as a negative resistance oscillator. The oscillation frequency is determined by a silicon abrupt varactor diode acting as a voltage-variable capacitor in a thin-film micro stripline resonator. This provides extremely fast
