eendelioe ff ASI, AT series of Abrupt PN-Junction Tuning Varactors utilize the lowest resistance & highest Q characteristics of optimized tuning circuit performance. Applications include both narrow and wideband frequency tuning through 12GHz. These devices are designed so the capacitance-voltage relationship closely approximates Square Law (n = 0.5).

Total capacitance is measured at 1 MHz and -4 volts on a Boonton capacitance meter. Standard tolerance + 10%. 2. Quality factor is calculated at -4 volts and 50 MHz, using values of Rs obtained at 1.0GHz and Cy.4 measured at 1MHz and the following equation: Qay=W/enfRsCy.4 3. Package style 51 is the standard package for this series of tuning varactors. These diodes are also available in the following package styles: 01, 10, 11, 15 (DO-7), 20, 21, 31, 83, 84. When ordering, specify package designation as a suffix to type number. ADVANCED SEMICONDUCTOR, INC. 4. Capacitance temperature coefficient: 300ppm/C max. at -4 Volts. Calculated from the following equation: TC= [C7(+85C)-C7(-65C)]106/ (85+65)C7(25C) average between -65C and +85C and is expressed in parts per million per degree centigrade (ppm/C). 5. Tuning ratio includes all capacitances, junction, package and all internal fringing capacitance (C7=Cy+Cp), from 0 valts to the rated breakdown voltage.
