VARACTOR DIODES
Surface Mount SOT23 Abrupt Junction
RoHS Compliant
DESCRIPTION
The GC1200 - 23 series varactors are silicon abrupt junction devices.
They provide the highest Q and lowest series resistance available in a 30
volt silicon device. They are ideal for narrow to moderate frequency
bandwidth applications, and are available in values suitable for HF
through 1500 MHz. The economical SOT23 package is ideal for
commercial surface mount construction and is available in single (23-0)
and common cathode (23 - 4) configurations. Some limitations apply,
consult factory for availability.
This series of diodes meets RoHS requirements per EU Directive
2002/95/EC. Consult the factory for details. The GCX1200 – 23 series
of SOT23 devices supersede the GC1200 – 23 series.

APPLICATIONS
The GC1200 series varactors are used for narrow to moderate bandwidth
tuning. They are available in values appropriate for HF through 1.5GHz
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%. Consult table below for standard
configurations.
