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).
Storage Temperature: -65°C to +175°C
CT = TOTAL CAPACITANCE
CP = PACKAGE CAPACITANCE
CJU = JUNCTION CAPACITANCE AT ZERO BIAS
VBIAS = APPLIED REVERSE VOLTAGE
q = CONTACT POTENTIAL OF THE DIODE (0.6 - 0.8 VOLTS)
n = SLOPE OF DIODE C-V CURVE (0.5 FOR ABRUPT JUNCTION)
These diodes are suitable for Transistor, Gunn and Impatt Voltage Controlled Oscillators; AFC Loops
and Amplifiers; Tunable Filters; and Linear Frequency and Phase Modulators
All of the abrupt tuning varactors meet or exceed the environmental specifications of
MIL-S-19500, MIL-STD-202 and methods from MIL-STD-750 that specify mechanical, electrical, thermal
and environmental tests.
