Tuning Varactors
30 VOLT ABRUPT JUNCTION VARACTOR DIODES
DESCRIPTION
The GC1500 series varactors are silicon abrupt junction
devices. They offer the highest Q and lowest series resis-
tance available in a 30 Volt silicon varactor.

APPLICATIONS
The GC1500 series varactors are used for narrow to
moderate band width tuning. They are available in val-
ues 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.
Standard capacitance tolerance is 鹵10% Other capaci-
tance values and custom mechanical configurations are
also available. All specifications shown are based on
style 30 package and include .18 pF case capacitance.
Consult package outline section of this catalog for other
case styles available. Complete electrical and mechani-
cal data is also provided.
