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.
