Description
HP VTO-9000 Hyperabrupt Series
oscillators use a silicon transistor
chip as a negative resistance
oscillator. The oscillation fre-
quency 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 commer-
cial 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 50volts in conven-
tional oscillators.
The VTO-9000 Series VTOs are
packaged in TO-8 transistor cans
for simple installation in a
conventional 50-ohm
microstripline PC board. They
are ideal for most compact
lightweight commercial and
military equipment designs.
Test fixturing is also available for
lab bench test applications. See
the “Test Fixtures for TO-8
Packages” section for additional
information and outlines.
Applications
The VTO-9000 Series oscillators
may be used in the same applica-
tions as VTO-8000 Series oscilla-
tors. The VTO-9000 Series is the
desired choice for superior
linearity and modulation sensitiv-
ity requirements.
