GCX1202 – GCX1217 VARACTOR DIODES Surface Mount SOT23 Abrupt Junction ® TM RoHS Compliant KEY FEATURES DESCRIPTION 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 www.MICROSEMI.com 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. Highest Q Lowest RS Large selection of capacitance values to chose from Low phase noise RoHS Compliant1 APPLICATIONS/BENEFITS 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. HF through UHF Band VCOs VVF (Voltage Variable Filters) Phase Shifters Standard capacitance tolerance is ±10%. Consult table below for standard configurations.
