Description
HP VTO-8000 Series oscillators
use a silicon transistor chip as a
negative resistance oscillator. The
oscillation frequency is deter-
mined by a silicon abrupt varactor
diode acting as a voltage-variable
capacitor in a thin-film micro-
stripline 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
as possible to maximize ∆V/∆T
characteristics for excellent
tuning speeds. Used in a phase
locked loop PLL circuit, a VTO
provides a receiver LO with
stability equivalent to the refer-
ence oscillator (usually crystal
controlled), yet variable in
discrete steps or continuously
depending on the PLL
Applications
configuration.
Frequency agile systems, such as
digitally controlled receivers and
active jamming transmitters often
use externally linearized
Another important aspect of VTOs
used in an LO application is their
power vs. frequency flatness
(± 1.5 dB).Thisassuresthatoncea
receiver mixer is biased for best
dynamic range the local oscillator
drive will remain constant
throughout the tuning range
without complex leveling
VTO-8000Seriesoscillators.
Typical settling times for the
VTO-8090are<200 kHzwithinone
microsecond while the VTO-8950
settles to <2 MHz within two
microseconds referenced to ten
milliseconds.TheVTO-8850
combines a bipolar transistor
oscillator with a GaAs FET buffer
stage. This GaAs FET buffer
isolates the oscillator from
varactor-tuned oscillators. HP
oscillators are monotonic making
external linearization easy using
analog (opamp) or digital
(EPROM) linearizing techniques.
The HP VTO Series has been
designed with a tuning input
bypass capacitance which is
sufficient to provide the neces-
sary RF filtering action yet as low
circuitry.

Description
clamp is placed over the device
under test and secured by ma-
chine screws prior to testing.
Orientation of pins can be verified
by comparison with part (c) of
Figure 15. It is recommended that
both machine screws be used to
fasten the ring clamp. Screws
should be tightened down snugly
with a jewelers type screwdriver.
