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
voltage variable filters and phase shifters. Additionally, due to their higher V
B
, they
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.
Most or our devices are supplied with
Gold plated terminations. Other
terminal finishes are available on
request. Consult factory for details.
