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.

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.
