Strict material and process controls result in high reproducibility. A unique silicon dioxide passivation process assures greater reliability and Excellent Efficiency low leakage currents at high temperatures. High Output Power 1 RoHS Compliant Diodes are available in various capacitance ranges for each of the 4 voltage ratings. These diodes represent the lowest transition time (snap time) available for each voltage rating. Unless otherwise specified, capacitance will be within the range shown below for each type. A capacitance tolerance of 10% is available at an additional charge. Diodes can be optimized for custom electrical or mechanical specifications. Custom parameters for capacitance, voltage, transition time, series resistance, etc. are available upon request. All specifications shown above are based on the style 30 package. Many packages options are available, including 150A, 35, 36, 42 and 56. Chip mounted on carriers with gold wire/ribbon leads are also available. Other package styles are available to meet specific requirements. Some limitations apply. Contact Microsemi for details. APPLICATIONS APPLICATIONS/BENEFITS The GC2500 series of step recovery varactors are used as harmonic Harmonics Generation generators for all orders of multiplication X2 through X20 for both narrow and wide bandwidths. Applications include local oscillators, Local Oscillators voltage controlled oscillators, frequency synthesizers, and up Frequency Synthesizers converters. They are also used in comb generators to generate a Up Converters broad frequency spectrum and in high speed pulse shaping circuits.
