CONTROL DEVICES

60 Volt Abrupt Junction Tuning Varactors

TM

®

RoHS Compliant

DESCRIPTION

The GC1700 series varactors are silicon abrupt junction devices. They offer the

highest Q and lowest series resistance available in a 60 Volt silicon varactor.

This series of diodes meets RoHS requirements per EU Directive 2002/95/EC.

The standard terminal finish is gold unless otherwise specified. Consult the

factory if you have special requirements.

APPLICATIONS

The GC1700 series varactors are used for moderate bandwidth tuning. They are

available in values appropriate for VHF through KU band frequencies. These

devices are best used in low phase noise voltage controlled oscillators, low loss

offer superior, low IMD performance over lower voltage types.

Standard capacitance tolerance is ±10%. Other capacitance values and custom

mechanical configurations are also available. All specifications shown are based on

style 30 package and include 0.18 pF case capacitance. Consult package outline

section of this catalog for other case styles available. Complete electrical and

mechanical data are also provided.
