GC1710

GC1700A – GC1720 TM ® CONTROL DEVICES 60 Volt Abrupt Junction Tuning Varactors RoHS Compliant DESCRIPTION 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. KEY FEATURES  Highest Q for 60 Volt Varactors  Lowest Rs www.MICROSEMI.com 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.  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. Most or our devices are supplied with Gold plated terminations. Other terminal finishes are available on request. Consult factory for details. 1 APPLICATIONS/BENEFITS  VHF to Ku Band Tuning  VVF (Voltage Variable Filters)  Phase Shifters ABSOLUTE MAXIMUM RATINGS AT 25º C (UNLESS OTHERWISE SPECIFIED) Rating Minimum Breakdown Voltage @10 uA Maximum Leakage Current @55 Volts Operating Temperature Storage Temperature Thermal Coefficient of Capacitance @4 Volts Symbol VB IR TOP TSTG TCC Value 60 0.02 @ 25 ºC 2.0 @125 ºC -55 to +125 -65 to +150 300 Unit V uA ºC ºC ppm/ ºC GC1700A – GC1720 IMPORTANT: For the most current data, consult MICROSEMI’s website: www.MICROSEMI.com Specifications are subject to change, consult the factory for further information.
