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 resistance available in a 30 Volt silicon varactor.
RATINGS
Minimum Voltage Breakdown: 30 V at 10µA Maximum Leakage Current at: 25 V and 25ºC 0.02 µA 25 V and 125ºC 2.00 µA Capacitance-Temp. Coefficient: 300 ppm/ºC at VR=-4V Operating Temperature: Storage Temperature: -55ºC to +150ºC -65ºC to +200ºC
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.
