VARACTOR DIODES

Surface Mount SOT23 Abrupt Junction

TM

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.
