They provide the highest Q and lowest series resistance available in a 30 Lowest R S volt silicon device. They are ideal for narrow to moderate frequency bandwidth applications, and are available in values suitable for HF Large selection of capacitance through 1500 MHz. The economical SOT23 package is ideal for values to chose from commercial surface mount construction and is available in single (23-0) and common cathode (23 - 4) configurations. Some limitations apply, Low phase noise consult factory for availability. 1 RoHS Compliant 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 APPLICATIONS/BENEFITS HF through UHF Band VCOs The GC1200 series varactors are used for narrow to moderate bandwidth tuning. They are available in values appropriate for HF through 1.5GHz VVF (Voltage Variable Filters) frequencies. These devices are best used in low phase noise voltage Phase Shifters controlled oscillators, low loss voltage variable filters and phase shifters. Standard capacitance tolerance is 10%.
