30 VOLT ABRUPT JUNCTION VARACTOR DIODES
DESCRIPTION
RATINGS
The GC1500 series varactors are silicon abrupt junction
devices. They offer the highest Q and lowest series resistance available in a 30 Volt silicon varactor.
Minimum Voltage Breakdown: 30 V at 10µA
APPLICATIONS
Capacitance-Temp. Coefficient: 300 ppm/ºC at VR=-4V
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.
Operating Temperature:
-55ºC to +150ºC
Storage Temperature:
-65ºC to +200ºC
Maximum Leakage Current at:
25 V and 25ºC
0.02 µA
25 V and 125ºC
2.00 µA
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.
