These devices are used in circuits requiring a high Q voltage variable capacitance such as: tunable filters and amplifiers, voltage controlled oscillators, frequency synthesizers and con- tinuous phase shifters. They are also useful as frequency and phase modulators in communications applications. JUNCTION CAPACITANCE (c) pF ATT TTT Standard capacitance tolerance is 10%. Diodes can be opti- mized for custom electrical or mechanical specifications upon Gc1600 request, REVERSE BIAS SCALE INCLUDES WORK @ct600A FUNCTION FOR SILICON (6=,7 VOLTS) 1 All specifications shown on the following page are based on 10 pot til bo the style 30 package. Other ceramic or glass packages are 1.0 to 100 Vp (VOLTS) available. Chips mounted on carriers with gold wire/ribbon Typical Junction Capacitance vs Reverse Bias ieads are also available. es om r +z a) . 9 > et) an on oO ee] 142) FREQUENCY SOURCES SCMICONDUGTOG FAVIBION 8 LORAL/FREQUENCY/SEMICOND 2>ND 96D 00797, D AO?-~F 45-VOLT % mm 5579621 9000797 7 SILICON TUNING VARACTORS ELECTRICAL SPECIFICATIONS T A= 25C - TOTAL CAPACITANCE! | QUALITY FACTOR2 | CAPACITANCE RATIO! ~ MODEL (AT -4V, 1 MHz) (AT -4V, 50 MHz) (Cio/Cyq5) NUMBER Cig (pF) Q_4 (MIN) GC1600A 0.6 3000 4.0 GC1600 0.8 2900 4.2 GC1601 1.0 2800 44 GC1602 1.2 2800 45 GC1603 15 2300 4.8 GC1604 1.8 2300 49 GC1605 2.2 2200 5.0 GC1606 2.7 2000 5.2 GC1607 3.3 2000 5.3 GC1608 3.9 1900 5.4 GC1609 47 1900 5.4 GC1610 5.6 1700 5.5 GC1611 6.8 1700 5.5 GC1612 8.2 1500 5.6 GC1613 10.0 1500 5.6 NOTES: 1.
