VCOs have a wide variety of applications where very

fast tuning speeds are required. This feature along

with our superior output power flatness performance

is critical for requirements in radar receivers or for

rapid generation of jamming signals in ECM

transmitters. When high frequency stability is

required for radar, communications synthesizers or

frequency

converters,

these

VCOs

may

be

integrated into phase lock loop circuitry. Low phase

noise performance of the VCO, with our highly linear

tuning, simplifies loop filter design and enables the

designer

to

achieve

superior

synthesizer

performance. These VCOs can be qualified for high

reliability

and

military

requirements.

The

accompanying table is an example of our standard

VCO designs. A wide range of custom designs are

also available with output frequencies to 6 GHz.

Please contact the factory to discuss your

requirements.

Description

These designs utilize silicon bipolar devices as the

negative resistance generator. The frequency of

operation is determined by a varactor diode that

serves as a voltage variable capacitor. Silicon

hyperabrupt varactors offer the lowest phase noise

performance. Careful selection of the varactor

diodes

manufactured

in-house

provide

linear

monotonic tuning characteristics requiring only

simple external driver circuits.

This range of VCOs is constructed using discrete

chip device integrated onto a conventional alumina

substrate or on a Glass Microwave Integrated Circuit

TO-8

SMT

packages.

These

packages

are

hermetically

sealed

using

resistance

weld

techniques. This compact rugged construction

allows for simple installation on either through hole

or surface mount PCB, and finds a wide range of

applications in demanding military, hi-rel and

commercial systems.
