Overview
Varactor-Tuned Oscillators Technical Data VTO-8000 Series Features • 600 MHz to 10.
5 GHz Coverage • Fast Tuning • +7 to +13 dBm Output Power • ± 1.
5 dB Output Flatness • Hermetic Thin-film Construction 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 microstripline resonator.
This provides extremely fast tuning speed, limited primarily by the internal impedance of the user-supplied voltage driver.
Fast settling is another feature of the HP VTO-8000 Series oscillators.
Typical settling times for the VTO-8090 are <200␣ kHz within one microsecond while the VTO-8950 settles to <2␣ MHz within two microseconds referenced to ten milliseconds.
The VTO-8850 combines a bipolar transistor oscillator with a GaAs FET buffer stage.
This GaAs FET buffer isolates the oscillator from variations in load impedance ...
