DESCRIPTION
HP VTO-9000 Hyperabrupt Series oscillators use a silicon transistor chip as a negative resistance oscillator. The oscillation frequency is determined by a silicon hyperabrupt varactor diode acting as a voltage-variable capacitor in a thin-film microstripline resonator. This provides extremely fast tuning speed limited primarily by the internal impedance of the user-supplied voltage driver. This family of oscillators is similar to the standard commercial VTO-8000 Series except for the incorporation of a silicon hyperabrupt varactor tuning diode. This enables the oscillator to be tuned over the specified range in less than 20 volts rather than 40 to 50 volts in conventional oscillators. Test fixturing is also available for lab bench test applications. See the “Test Fixtures for TO-8 Packages” section for additional information and outlines.
