GC1700A - GC1720 (R) TM CONTROL DEVICES 60 Volt Abrupt Junction Tuning Varactors RoHS Compliant DESCRIPTION KEY FEATURES The GC1700 series varactors are silicon abrupt junction devices. They offer the highest Q and lowest series resistance available in a 60 Volt silicon varactor. Highest Q for 60 Volt Varactors 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. www.MICROSEMI.com Lowest Rs Large selection of capacitance values to chose from Low phase noise RoHS Compliant1 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 VB, 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. 1 Most or our devices are supplied with Gold plated terminations. Other terminal finishes are available on request. Consult factory for details.
