30 VOLT ABRUPT JUNCTION VARACTOR DIODES

DESCRIPTION

The GC1500 series varactors are silicon abrupt junction
devices. They offerthe highest Qand lowest series resis­tance 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 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.

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 .18 pF case capacitance.
Consult package outline section of this catalog for other
case styles available. Complete electrical and mechani­cal data is also provided.

NOTES:

1. When ordering, specify the desired case style by adding its number as a suffix to the model number.
Some limitations apply - consult factory for details.

2. These values include a package capacitance of .18 P

3. Q is calculated from: Q=

= Series resistance measured a 1 GHz using transmission loss techniques. Capacitance is measured at 1 MHz.
